I have a tach I want to install in my Bronco but I don't know how to hook it up to the coil/pack thing on ym fender wheel. I have the instructcions that came with it but I don't know which wire I use from the coil/pack thing. It says hook up to negative but which wire is that? Any help is greatly appreciated

The green wire, if I remember right, is the one that goes to the coil and to the computer. Worst coms to worst to the key on and use a test light to find out which one had a constent 12 volt and which one pulses with the turn over of the key. Also if yours has a noise supressor(condensor), it comes off of the negative side of the coil. My 85' BII had a plug in, available for the diagnoistics, that a spade connector would plug right into.

Yep, green wire on the coil sounds right. Tie the light into your dash lights, so your dimmer works.

Green wire is correct! Hopefully one day I will have a enough motor to justify my tach LOL! Until then, it looks cool and everybody asks..."you got a V8 in there?"

I Whish

How do you think I feel I got a 5 inch Auto-Meter monster tach for a gift and the only thing I have to put it in is my Bronco. So I have a stock Bronco with a HUGE tach in the corner of my dash...
