Just FYI here's a pic of the stock front locker setup. The silver doohickey in the middle with the white line is the vacuum/electric switch that activates the blinking warning light for the front locker.
Not needed for front locker addition, just nice to have if you can find one for authenticity.
And this is the blinker circuit board that plugs into that extra terminal on the locker panel wire harness.

No sorry, that's the only picture I took of it, no longer have that van. Microbusdelux has it now.
I found the thing just hanging from the wire harness, no mounting! _________________ Currently:

Dangling was probably how it was from factory since they put the foam on it anyway. _________________ Silicone Steering Boots and 930 Cv boots for sale in the classifieds.

Thanks for the video!
I never bothered installing the blinking stuff on mine, a retrofit front locker.
I think this was just a device to not get sued by the consumer in case shit went wrong.
I mean, do you even see it blinking if it were to be pulled on it accidentally while driving? My eyes are on the road hundreds of yards ahead, I don't see these lights... _________________ Silicone Steering Boots and 930 Cv boots for sale in the classifieds.

Hello. I’m installing the syncro locker panel and I can’t quite locate where to plug in the black/blue wire that Alika refers to as #15 behind the emergency flasher warning switch.
Can someone please explain me where does it go exactly? A picture for reference would be great. Thank you! |

Just FYI - This diagram is for the cruise control system. Has nothing to do with Syncro front locker setup.
#12 is the vacuum plunge device to the throttle, #11 is the electric vacuum pump for the cruise system. Again, not connected to locker system. _________________ Currently:

If you have the Syncro locker harness this is really pretty simple.
The locker harness should have a single black/blue wire with both a male spade and a female spade near the end.
This single black/blue wire is for power for the locker harness.
On the back of the hazard/flashers switch is another black/blue wire with a female spade plugged in to provide fused power to that switch.
Unplug that female spade from the switch and plug it into the male spade of the Syncro locker harness.
Lastly, plug the female spade of the locker harness onto the male spade of the hazard/flashers switch.

That is very good to know! It was given to me by someone from Germany a while back in reference to the lockers...I really never looked too closely at it. _________________ This free advice is worth exactly what you paid for it.

I got here too late, but look at the back of the emergency flasher, there are numbers. #15 is where the blue/black wire goes like explained above, it's connected in parallel, it's very plug and play. _________________ Silicone Steering Boots and 930 Cv boots for sale in the classifieds.

Thanks guys. I think I got it figured out. One thing that is still not working for me is the individual lights don’t come on when I pull the knobs. The whole panel lights up when I turn the light switch on but not the lockers and decoupler lights when engaged. Since the main illumination light comes on that means I have power going to the panel right? Not sure what exactly should I look for when it comes to the locking light indicators. Any suggestions are appreciated!

Jump the connector with a paper clip at the locker switch. It should light. If not, use a voltmeter to see if you get continuity to ground from the switch connector. The switch puts the circuit to ground (if i recall correctly) _________________ Silicone Steering Boots and 930 Cv boots for sale in the classifieds.

I’m troubleshooting my locker panel lights and it seems like for me it came down to my circuit board. My panel illumination light works just fine. I took the light power wire and ground and touched the metal connectors and it lights up. But when I connect the power wire to where the ignition power is supposed to be and ground the individual locker and decoupler circuits none of the lights come on. All the light bulbs are brand new and work in the panel illumination spot. Is it possible that my circuit board is bad? Am I missing something? Thank you for any suggestions.

A multimeter would be an obvious tool to track down these issues. You can verify both power and ground that way without relying on a bulb. A unit that measures DC voltage and audible continuity can be had even on a cheap unit if you don't already have one.
LEDs are also sided, the will only illuminate if installed in the correct orientation. Any decent retailer should have that in their description. |

As ^said^, LEDs (often) have a plus and a minus orientation.
If they don't illuminate, remove, rotate 180° and re-insert the other way.
Where did you get those LEDs? _________________

In this case a simple test would be to put the ground wire on the +15 pin on the board and then touch the 12v power wire on each of the locker contacts 1 at a time.
That will reverse the polarity of each light and show if it simply needs to be turned 180 degrees.
