97 GrandAm Wiring

I was checking out the wiring diagrams on this site and at designtech. Wiring diagrams do not match. DESINGTECH                      THIS SITE Start:        Yellow -----------Yellow     Ignition #1: Pink -------------Pink Ignition #2: White ------------White Ignition #3: N/A --------------Brown ACC:          Orange -----------Orange Ect. When I looked at my car, it has the Brown one. Does that mean that I must install another relay for the Brown one too?? Remote starter is installed but I have a couple of bugs with it. I have the AstroStart 803, which has a built in relay for the second ingnition wire but not a third.CementBrain

It, too only shows Pink and White Ingnition wires, I seem to have 3. PINK, WHITE and BROWNCementBrain

mo12V -- Where did you get your info. That's 2 for 2 now.CementBrain

MICRO, OMEGA, DEI, & 20 years of stuff

There R many companies that offer wiring charts.  We always look at 2 or 3 charts to compare before we do any work.  But we ALWAYS check wires before hooking up.  Then we record the difference. 

In an attempt to get as much information as possible to install shops A.S.A.P. U really have to double check.
