Need a little help with some wiring issues for a remote start on my 04 Dmax, just got it and love it. I was wondering where is the tac wire and is it positives and where is it located, I have read some post that its under the steering wheel column in the bulk of connecter and is white. Also the other wire need is the positive for the glow plugs??? Any help would be appreciated.

Tach wire is white behind the instrument cluster. Check with a DMM it should be 0-5v ac and should increase with rpm. As for the glow plug wire it is NEGATIVE and is blue behind the instrument cluster as well. Should be - when the glow plug light is on.

Thanks for the info its what I found but wanted to be sure.
