Alright... I'm working on the last bits of wiring for my 1Z swap in my 02 MV, and a few confusing challenges have arised.
Firstly, I'm trying to get power to my cluster. I was really excited to use the B4 cluster for this swap, for both the looks and simplicity. E/2 and D/8 are both jumpered at KL15 at the top of the fusebox, and U2/1 has been relocated to U1/4.
With ignition off, the LCDs are on, but they die once ignition is on. I even took U2/1, added a single connector to it, and plugged it directly into KL15, which I know for a fact is getting 12v with ignition on. Still a dead cluster. I unplugged E/2 from KL15 and plugged the VR6 cluster back in.
The LCDs worked with the ignition on and off, but I ended up burning a large segment of the circut board, and I'm still trying to find the reason for that. I couldn't get the backlight to work either. Crossing my fingers I haven't burnt up two clusters at this point.
Secondly, I'm having an issue with my brake lights. Originally, an 02 EV uses the MK4-style 4-pin brake pedal switch, in which I cannot find the original connector for (I believe it's on the VR6 harness). I used pins E/3 and 4 with the Passat's switch and connector, but I'm still not getting anything.
Hopefully you see this, Justin! Any advice is greatly appreciated!
