after work i decided the have a 2-3 hour work session, which turned into 6 hours.. Rolling Eyes

I'm not complaining though i had a blast. I'm not the most efficient worker in the world but heres what i got with a few friends, and a few nuisances with the car.

decided to put in a few hours of work. got everything out of the car. the cars ready for scrap any one have an idea how much you'd get for a car? I also have an extra auto Honda transmission to toss in there too. Also wiring seems like a partially daunting challenge but well see how it goes tomorrow.

up here in Michigan I got $250 for my Sunfire donor car. More than half the $400 purchase price. I remember pulling the motor was fun because of the anticipation of the project ahead.

thats exactly how i feel it gets more exciting everytime i work on it. every second is a great time until i run into little problems but ill have that. Cool i was curious about how much the thing would be worth. Smile

if the car's in all good shape and all try to sell it as an entire unit if you got ricers around your town. the subie boys round here are always needing body parts

right pressy4pie i was considering just throwing it on craigslist for a week or two to go fish with it, if i don't get anything then ill just take it for scrap. in the mean time i have got a lot of the wiring done i'm still looking for a exact pinout directly out of the ecu i might have found something.

also mounting the radiator. I think the one spot behind the engine in the back would restrict to much air flow but i dont think there would be much room in between the radiator and engine.

Heres just a few quick ideas i had.

hey guys ive got the whole harness stripped down and after a long day i ended up cutting the harness that goes the the engine instead of the transmission harness plugs are sort of similar but the set me back a few hours soldering and picking the harness back together its good to go.

now i face a problem of piecing the the relay rack and radiator harness back together i was never really great at this stuff Brick wall

DBUG if you are going to use the relay rack of 4 relays from the Subaru pull a relay out and look at it, the 2 copper connectors are the load and the 2 silver connectors are the control. Hook power to one side of the copper ones from a battery supply the other copper one to what ever it is to run (fuel pump, fans, ect.) Then on the 2 control wires when one side has power and the other ground it will turn on the fan or pump or computer. You can switch either the power or ground on the control side to make it work. Hope that helps. Mine started last week but only ran it for a few seconds because I didn't have the exhaust or radiator on it.

thanks ed that actually helped alot i never really thought to do that.
Also which car did you get all hooked up?
also my brain is kinda fried from working and working on this and i can figure out where im putting all the main power directly from the battery to anything should i use a distribution block or what im kinda stumped ive never done a project like this im used to fixing little wire from sensors not remodeling complete harnesses Confused

the adapter plate is on the way.

this is where im at so far.the engine connector wires are the sloppy mess hanging off the bottom right side and a bunch of extra wires going to the ecu are in a bundle on the left hand side. Didnt want to cut just incase they were important.

Also did you have to ground any pins for an automatic transmission inhibitor switch or anything for security? Or should it just start without a problem?

Mine that I started last week is in my Baja Bug I am building over on STF. On my Subaru there is no security and it was from a manual so nothing there either. I didn't ground anything extra but left a few wires exposed that may or may no need to be grounded but it started just like I ran it yesterday. I also left the speed sensor wire exposed incase I need to do something with it. I made a small panel with a ignition switch and the check engine light , oil pressure light and the alt light to test run the motor. I do have a code but I will deal with it later, it was either a O2 sensor code or a TPS code, I don't remember witch but I did not have the O2 sensor hooked up so that is what I'm thinking. On mine the O2 code is a 31 and the TPS code is a 32 so I need to recheck it later after I run it more.

nice to hear all worked out for you Ed, im really really hoping mine will start up like that! I need to figure out what im going to do with the vss. I'm sure the codes will be gone as soon as you hook it all up.

Quick question anyone know the inside diameter of the stock fuel lines are? (the rubber ones)

After a long weekend of explosions, fishing, and grilling ive found time to work on the harness, still waiting on the adapter plate from KEP but i think i've found my radiator spot. im going to make my over flow tank a empty bottle of liquor. Not sure what kind yet Cool

Any who i think this should be a pretty reasonable spot, with decent air flow.

Also i don't know whats wrong with me but i can't figure out the wiring for the fan relays. Should i combine both fans into one relay? if i should how would i do it? If not how would you guys go about wiring it? should i take both ecu signal wires and combine or what if anyone can draw a diagram or something that would be great i just dont feel like using the original relay rack because its confusing me even more. Sorry for be annoying and asking to many question but you have to bare with me Rolling Eyes

thanks again guys

You don't need to use the relay rack, I used it because I am cheap and it was free Very Happy

Yes the way TimS did it one relay is running both fans but you could use two if you wanted. I am just going to Y the output wire from the relay for both fans.

right thats how i am too but now the dang things confusing me so im all for spending money on a little relay set up. Rolling Eyes

is it a two speed fan heres what im looking at

yes i misspelled white haha.

but my ecu wires are Green/Red and Red/Blue could you make a little wiring diagram for me i would greatly appreciate it like where to run the power wires to both sides and where to run the wires ( my guess would be ignition on) sorry i ask so much just want to make sure i dont mess anything up so id figure id ask the knowledgable guys. Very Happy

thanks,
Dustin

My fans are one speed. Your ecu wires supply ground for the control side of the relay. You put power to one side of the control side of the relay then the ecu wire to the other side of the control of the relay and when it gets to temp the ecu sends ground to the relay and it then turns on letting the power side of the relay send power to the fans.

Ed

DBUG Nist · Posted: Tue Jul 07, 2015 12:54 pm Post subject:

so yours only have two wires coming out of the connectors for each fan? but then it will probably just be easier wiring two rather than one because it seems like splicing both ecu wires together wouldnt exactly be the best idea or i could be wrong?

Also did you use the stock fuel filter for your build because i'm having a hell of a time figuring out the size of the fuel hose. (Between metal tubes for injectors and return to the filter)

My fans do not match my harness, I did not have a car I just bought a motor with the harness, computer and KEP adaptor but no flywheel for $300 off of Craigslist. So used another radiator I had. I am using a Chevy fuel pump and Chevy fuel filter. I think the Subaru fuel filter has 5/16" fuel lines.

I only have one fan control wire coming out of my ecu so one relay works for me, if you have two fan control wires coming out of your ecu you should use two relays. I don't have any info on the obd2 system.

awesome thanks Ed. Thats all i needed to know along with one more thing, is it really going to make that big of a difference from having a two speed fan compared to one? i mean its going to be doing the same thing might just take a touch longer to do it i guess. but how does this look for 1 relay?

Yes that is how to wire the relay. Maybe until you figure out what does what use both controls on two relays and wire one relay to one fan on high speed and the other to the other fan on high speed and watch them and see when they come on, just a idea.

Ed

DBUG Nist · Posted: Tue Jul 07, 2015 3:21 pm Post subject:

awesome glad to hear thats right ill draw something up after i get off work, and probably just bench test the wires to see what wire is what speed
