Re: aftermarket tach questions What year is your car?
You can access the correct wire from the top of the pcm. Run the signal wire thru the firewall.
With my Autometer tach I had to cut a wire in the back so it would read in the right mode. No Abbott thingamajig needed...

Re: aftermarket tach questions Someone else will have to chime in with the correct PCM pin-out for a '99 model, but you shouldn't need any sort of adapter to use this tach. Set it for 4-cyl, hook up the power, ground, tach, and wire for the lighting, and you're done.
Re: aftermarket tach questions On a '99 PCM on connector P2 (Red) it is pin #10, the white wire.
And as for you PSJ, [quote]No Abbott thingamajig needed...<hr></blockquote>you have a 4 cylinder capable tach you luck dog <img src="gr_images/icons/wink.gif" border="0"> With the typical factory style OEM tach, you don't have this option <img src="graemlins/gr_cry.gif" border="0" alt="[whiner]" />

aftermarket tach questions Hey guys,
I'm sorta a novice when it comes to wiring and the sorts but I bought an aftermarket sport comp monster tach for my 99 TA WS6 the other day and I decided to wire it up myself. My friend got a wire diagram from his work which didn't seem to help much. After taking off the dash I found that there was a big twine of wires which connects to the computer. Does anyone know which wire is the tach lead? And I understand I need a Abbott Electronic Ratio Adapter Box for the tach to read properly. Will this setup work?
Thanks for your help
