I have an 85 2.8 camaro with the huge fuel guage instead of a rev counter. I was wondering if it is possible for me to put a rev counter in my car? I don't mind having it bolted to the dash but I'm not sure where the cable would go...the engine or the gearbox???

Thanks for the help

Man I'm thinking the same thing. I want a tach too, just don't really know where to put it or how to hook it up. I hope someone can answer this b/c I've been dying to know where to hook it too for a while.

easiest way to get a tach, go tothe junk yard and yank an IROC gauge cluster, looks alot nicer, did it to my car, no more dummy lights, u actually have full gauges. all u do is yank the old one and drop the new one in. just change the oil pressure switch to a sender for a 350 and do the same for the temp switch. after the the cluster cost and sender costs i payed arould 85. thats less than u are gonna pay for a nice tach and u are gonna get alot more and something made for a 3rd gen

 

A tach is simple.. four wires. One for power, one for ground, one goes to your headlight circuit, and one goes to the ignition coil for the tach signal.

You would attach the signal wire to the gray connector on the remote ignition coil. The wire is black/white, terminal "B" on the coil. Use either a butt connector, or soldering to join the tach wire to the factory harness.

Don't use a blue splicing connector; I used one. Someone told me "No! It'll cut through the wire!" I told them they were nuts... about three years later my car stalled as I was driving. I pulled it over, and after doing the "wiggle a wire, try starting it" technique, I got the car to start. Turns out that splice connector did cut through the wires, it left me with two copper strands left on the factory harness.

Summit has a few good tachs.. I myself use a Sun mini-tach. I helped a friend install a Sun Super-Tach II on his '86 Monte Carlo. They also sell an Auto-Gage tach for $40, and they have some Auto Meter units around $80-$90.

Oh- location? Mine hangs from under the top of the dash, and blocks the driver's side a/c vent. When I had a/c in the car, I never used it anyway!
