Tach wire for command start

[Carl64]

Hey all; installing a command start in my car and am wondering where the tachometer wire is? I've found the harness under the hood coming off of the coil's but don't really want to tie in there; anywhere inside the car that I can go? Was thinking maybe behind the instrument cluster where it physically joins the tach.

Also wondering (although haven't looked for this wire) where the yellow starter wire is as it isn't with the rest of the ignition harness in the steering column.

I have installed many an aftermarket remote start in several different brand of vehicles. I took a look into installing one on my Redline, and deemed it to much effort. Let me know how it works out for you. Here is a wiring diagram. You can get it off of bulldogsecurity.com

Im moving along pretty good, about 3 days in and almost got it to the point where it starts the car lol. Thanks for the diagram; should help wasn't sure where the ECM/BCM was etc. However where is the "TACH WHITE or ORANGE IN PIN B or G @ MODULE, TOP LEFT OF ENGINE" located at? There is alot of modules by the oil fill cap lol.

I'll have to have my ol man look up a wiring diagram for me, although that still wont tell you exactly where it is, just where its wired to. I will look at the car tommorrow and see if I can find it. I really should remote start mine, I had a winter car two years ago, should have kept that. LOL.....
