Dumbarse needs help locating wire

[Sniper_xB]

Hey, I have been a reader of DSMTuners for a little while now, but this is my first post. I have been at a standstill and can not locate the tach wire. I have done countless search terms and come up witha few things, but mostly what I already knew (white wire.) I have a '97 GS and would like to tap into the tach wire for the Viper alarm. On my Scion xB it was easily available at the OBDII port, I assume it's there. The white wire which I am told is only putting out .15v at idle. Yes, my multimeter is set correctly at 20v and not 200v. Anyways, if someone could help me or post a pic, I would appreciate it. I looked at VFaq and it says on the 18pin connector it is #6, I thought that would be the OBDII, but thats a 16 pin port. (thats the one I'm getting .15v on) Alarm should only take an hour, it's now been about 4 hours installing and looking up info on the tach wire. It's the last thing I need to hook up, except the hoodpin, speaking of, anyone know a good place, most of the stuff I found is hard to get a tool to under the support bars and don't feel like drilling either. Heh, anyways thanks in advance.

PS
Would rather not go under the hood for the tach, nor behind the guage cluster unless absolutely have to.

Please fill out your car profile, I'm moving this to 420a bolt on tech so you can get better responses.

Awesome, thanks. I wasn't quite sure about that considering it was my first post on the forum, just put it in newbie.

well as you know our ECU's are under the hood of the car.....and our obd2 ports under the dash, so you might not have a choice about where you can hook up your tach signal at.

This is an install of the SAFC on our cars with some wiring locations, it might not be of much help to you since you already know the tach wire is white, but it might help you hink of something.

Thanks BigRand, I knew I could goto the ECU just didn't want to, woke up this morning/afternoon, and being fed up, just ran it to the ECU. All works perfectly.
