so i remember seeing someone sayin that there was a wire at the coil that i could get signal for my tach from cause i have no tach right now

i think jay or david b was the one who noted that. ask them.

Green/black at the coil. Within 1 inch of it's connector

It depends on if he's running OBD1 or 1.5/2. Later ones (1995 and on) have the coil integrated into the distributor, so the green/black wire comes to the distributor's connector there. Either way it ends up as the same wire.

anyone have a picture of the bluewhite tach signal wire? I am going to be trying to find mine here soon...I know it is supposed to be somewhere under where the maf used to be...is it part of a plug or anything? I would really like to have a tach lol.

if i can recall, its the neg. one right? hell dude, just power to the tach from ure battery, and add the wires onto each side. which ever side works. works

Yeah, It's down by where the engine harness connects, exactly where you just said. if you look at that picture I posted up, That was just an extension blue wire I used, and you can see it pretty much goes straight down that way

I was just looking at the write up thread again...I think I can find it based off of the picture there unless my harness got spliced all wonky...if thats the case i might pull the cluster...i hope thats not the case lol. The car actually has a msd coil so i should have no problem finding the signal wire at the tach...so i am not to worried about that...just the chassis tach wire..

Well, no matter which way you go it's easy. The tach signal wire at the cluster will be the the ground. Take that straight to the MSD signal prong, or it's ground. Easy peasy. The tach works from the pulses given off from the ground of the coil. That's the easy description of how it works

i thought that the tach signal wire at the back of the cluster would be the blue and white wire like what is supposed to come out of the fender beneath the maf...I understand how the tach works...i am just worried about finding the wire where it comes out in the engine bay. Its going to be so exciting tho to see how fast the car goes at what rpm after driving for 6 hours home with the only 2 working gauges being fuel and voltage...hahaha.

hahaha, there is no blue/white wire at the back of the tach...so i am going to hook the ground wire on the back of the tach up to the ground wire on the coil....i tried hooking up what i thought to be the blue/white wire up in the engine bay...but i didnt get any tach response...so the wire might be wrong or broken....oh well, hopefully this will work.

no.

u got black. for ground



red.

add a switch to the power source



and green, for tach signal, to the coil

is that hard?

lol....i figured the ground wire at the back of the tach would be the black wire..tach didnt work...tried the dark green wire...tach didnt work....tried the light green wire and tach works...so if you want to just run a wire from the back of the cluster to the coil...use the light green wire...


now i just need to figure out oil pressure and water temp and then all of my gauges will be working...but for now i have speed and rpm....woot.
