Hey guys.

I'm trying to hook up my stock tach in my 89 trans am..but I have no idea where to look. I know its probably a plug if I'm not mistaken, and plugs into the distributor, but I dont know where. I see two plugs on the right side of the distributor, but stuff is already plugged into them. What wire am I looking for..any help? any diagrams? thanks.

 

that car should be pre wired for the tach. so i guess i don't really know what you would have to hook up. but after market tach come off the coil not the distributor. if i'm not mistaken so does the stock tach.

 

Well we did an engine swap, it had a 305 F.I motor, we put a small block carbed 400 in it..I just dont know what to look for plug wise.

 

oh ok
it should be the white wire coming off the coil
i just looked it up for you. tap into that wire and you should be good.

 

Kinda a noob..the coil? The distribuator? The wire that plugs into the tach spot on the distribuator is brown..spliced into a red wire.
