I have my window switch mounted in the car. what is the easiest way to get hooked up to the tach wire from inside the car?? wire color??

 

I think you need to go to the PCM...what car.

 

Assuming your car is an 02 I am pretty sure it's the #11 wire on the PCM. I know it is white but there are several white wires coming out of it so make sure you have the correct one. Also, you could probably run the wire through the hole in the firewall where all the PCM wires come through.

 

My tach wire is number 10 wire on the PCM, I have a 2000.

 

yes the car is an 02.. if someone could verify if its no. 10 or 11 that would be great!!! Ill have everything wired up once that wire finds its home. The Digi switch is mounted under my arm rest so ill shoot the wire up through the gromet which already has no2 line, 2 ga trunk battery wire, fan switch, and,and, and,

I think it came out pretty good though.

 

Yes it's the #10 pin, White wire on the Red PCM plug.

 

Put mine there too except mine's in the bottom, call mine my "flux capaciter"

 

Cool deal!! Thaks everyone.. ill go wrap this up

 

There is no connection on the (other plug) blue plug at 10 so you can't hardly mess up!! There are several white wires as stated.

 

I was quoting Matthew Harlan's instructions for a shift light, wasnt looking @ the PCM plugs at the time. Thanks though for the LS1 trivia answer though.

 

well if i have a shift light all ready spliced in the tach wire, could i slpice in to the shift lights wire or threw the pcm again?

 

Don't know what you are talking about...but I was referred to the blue plug at the PCM for tach wire once on this illustrious forum - incorrectly. Thought i'd echo some clarity.

 

That's exactly what I did.

 

Dang that sucks, I see what you mean. Thanks

 

I spliced into the shift light wire- no probs so far
