Starter, reverse light solution for manual swap, at 175 relay

[EuroTec]

Many questions about this issue so I'm here to post this solution so folks can find it in a search.

So you've done a manual swap in your Eurovan, you've installed my Transmission Emulator, but now it won't start and the reverse lights don't work.

Here's the fix.
First you have to get at the 175 relay also know as the park neutral relay or PNP relay. It lives under you center dash area where the radio and climate control are located. There is a panel in the middle that runs full width of the center console with four screws holding it on. Remove the four screws, lift out the panel and you should see a bank of three relays.

The one you want has 175 printed in big numbers on the top. They can be a real pain the arse to remove! A little spray of WD40 might help but go sparingly. If it's being really stubborn, remove the positive battery cable from the battery so you don't fry anything and use a flat blade screwdriver to pry the relay from it's socket. Work your way around all four sides.
Once it's out you'll need to remove the black plastic cover. Carefully pry one side at the little retaining tab and lift the relay assembly up.
DO NOT POKE THE SCREWDRIVE IN TOO DEEP AS YOU WILL DAMAGE THINGS!!
Now repeat on the opposite side. Once you get it past both sides it will slide out.

Time to test your soldering skills. Solder a jumper wire in place like in the photo below.

Now slide the cover back on, it will go only one way so be patient and get it right. If you have some dielectric grease, apply it to all terminals and install the relay. That's it. Turn the key and the car should now start.

On to the reverse lights.
They are operated by the same relay so you'll need to get at the wires that come out of the relay's socket. You can remove the socket from its holder.

Get two lengths of wire long enough to go from the relay, across the dash to the left then thru the firewall and down to the reverse light switch. Twist them up like a long rope for easier routing.

OK on the relay socket, locate the BLACK/BLUE wire at the center terminal #5. This wire is 12V hot in on or start key positions. Use a wire connector of your choice to tap into this wire and attach one wire of the pair you just made to this wire. You want to leave it connected to the relay and wire harness with your new wire connected to it.

Now locate the BLACK/GREY wire on the relay socket terminal #4. CUT this wire. Ignore the wire left on the relay side. Take the part of the grey/black wire that is still connected to the wire harness and connect the other wire of your pair to it. Route the wire pair to the reverse switch and connect it to the special EV1 connector of the switch and attach to switch. Provided the switch is good, the reverse lights should now come on when you are on reverse gear.

See diagram below for a visual on this.
