I just bought a tachometer for my 85 truck. the package says that i need to connect a wire to the ignition coil, but the truck doesn't have one. any ideas on where to connect it?
thanks josh

 

its got one, or else it wouldnt start

 

well it has an igniter but i didnt see a ignition coil.

 

The coil is mounted on top of the igniter, just follow the coil wire (middle wire) on the distributor back to the coil.

 

There should be a green plug coming off the coil

It's a single wire w/ a single green plug. Just hook into that. It's really easy.

 

I found the wire coming out of the coil with the green plug. I spliced into that wire but the tach still won't work. The needle starts out straight down, then goes right to the 8 and rests there. When I rev the engine the needle goes counter clockwise from the 8 back up to the 4 or 5. Do I hvae something backwards?

 

how many threads are you gonna start about this tach?? YOu most likely have a bad tach... my friend went through 2-3 sunpro tachs before getting one that acutaly worked

 

did you make sure the switch on the bacck is set to 4cyl and not v6 or 8

 

Sorry about all the threads, i just couldnt figure it out. but yes the switch is on 4, i guess it is just bad.

 

I have a 85 runner that was converted to carb. I have an ignitor out of an 83 pickup and I am trying to use the stock SR5 tach. Does anyone know what wire to connect the ignitor wire to. I have checked the wiring diagram and traced what I thought to be the tach wire in the factory harness from the cluster to under the hood. It still does not work.
