im looking for the wiring diagram and the passlock immobolizer part number for:

98 Pontiac Grand Prix GTP Auto

Currently i have the Viper 160XV Remote Start/Security, but I plan on just installing the remote start because the vehicle has a stock keyless entry/security.  Again I'm looking for the wiring diagram for the GTP, where and what color the tach wire is, the ignition harness(es), and so forth aswill as the best possible places to solder/tap the viper onto the vehicle harness.  the other request is the bypass module for the passlock and the wiring schematics for it.  I do thank you guys for all of your help, i had alot of help from the past from the people on this site, my applause to you all.

p.s.-i have an AIr/Fuel Gauge i want to install, where is the O2 sensor signal wire located in the engine bay?

after much searching i realize that starting after 99+ that the grix's has the passlock III, i currently have a 98, would that mean that it has the passlock II on it?  if so what DEI bypass module would i need to get pass it?  i know for my 99 cavalier i needed a 555L, what part number from DEI would i need for the 98 grand prix?  also i found the wire laout in the other forums, but my question was if i could just skip the viper security and just install the remote starter on the vehicle.  thanks.
