I would think by the distributor or maybe the coil is where you would find a the wire to run your tach with. I always just pushed my tach wire into the harness on the distributor and found the wire that way. But, I've never hooked up a tach in these Vans before. :shrug:

Yes, but there is a factory pigtail for the tach wire. I want to say its on the passenger side in the wiring harness. I've seen it before but can't think were its at.
Oh man I just put my doghouse back on I could have peeked around for it. Oh well next time! :D

apparently there isn't a factory pigtail for tach on 96 and up. from your pic,
the yellow w/black line wire (negative) at coil is where tach trigger wire gets hooked to. soldering is recommended.
Thank You

Sorry for digging this old thread up...........what wire ended up working for you?

On my '96 I have 3 wires going to the coil: white with black stripe, pink, yellow(no black stripe).

I tried hooking up my used tach I got off a friend for free to the white with black stripe, but no worky. Just wanna verify that is the right wire for my '96 if anybody knows before I smash this piece of crap tach into a billion pieces with my trusty BFH!!!!!! :banghead:

Thanks! :chevy:
