tach wire
 

does anyone kno which wire is the tach wire on a 96 ob2 pcm?

V8 Coil or White PCM Firewall from the12volt.com looks like the white wire I usually go to coil since there is more room and it's easier to get to it to weatherproof and solder

do u have any pics or diagrams of the wire on the pcm u are talking about and which wire do u tap into on the coil u are talking about?

it's the white one at the coil no pics

see i dont have my car right now its at the body shop getting my hood painted is there only 1 white wire on the pcm or many if so which white one can i tap into on the pcm, thanx

not sure but I think there are 2 white wires

hmm guess ill have to check my dad's all data next week
