i did the diode mod to my VW T4
Weird! Would be a Bosch one as standard, thick red B+ and blue +61.
Please explain in more detail. Like saying. You stood in a bucket, pulled the handle and you floated 2’ in the air.
As for GTO. I THINK it’s the same set up as the FTO.
Small module side of head. Four or five wires. Black/white in/out ign + to coils. One ground. Not sure out one to capacitor on side of head, then one to the tachometer.
Found this out about 14 years ago, non start FTO since driving under a tractor, came in as non start. Joined the two black/white. Via 10amp fuse and high ho silver away. Just no tachometer Lol
