How do you disconnect the TWCU in an 86 z31 2+2? I'm having all sorts of strange problems with the electronics, like the security light flashing constantly (the battery is draining and I think this is why), the headlights turn on on their own, but don't come up, the horn was going off randomly and when I turn the key, it will turn over, maybe run for like a second, and then die. Then every time I try after that initial one, it won't even run at all- but will still turn over. I was thinking that there was somehting fishy going on with the alarm and hoped that by disconnecting it, I could remedy it all. Any ideas? Thanks!

 

Check your charging system!!!
