Alright guys I'm gonna need your help on a few things. I'm gonna be installing a Viper 791xv in a 1990 240sx Fastback SE. What Im gonna do is create a Wiring diagram that will show the brain, remote start relay and how it wires up to the stock wiring harness as well color coded wires. The purpose of this is to make it that much easier to install the alarm, the other guides on here are helpful but some things arent clear and pics are always extra helpful. Also I want to be able to depict whats optional and whats needed to make the install easier for some of us.

The wiring diagram will be for a 1989-1994 240sx S13 SE. So thats power windows, power locks etc etc. This will just be keyless entry with the alarm and remote start. No fancy things like Pimp My Ride where you push a button and a screen flys out.

So I'm gonna go through all the wires on the system and I'm gonna list the wires they correspond to the S13. If I get something wrong correct me and if its optional state so and if its blank fill it and I will edit it. After we go through all the wires and everything is correct than I will create a wiring diagram and post it up.

H1/4: Optional can be removed and Depinned?

H1/5: Red/White at Dome/Roof Light

H1/7: Not used as 240sx use Negative door style switch.'

H1/8: Chassis Ground

H1/9: Empty

H1/10: Red wire from the siren.

H1/11: White Wire on the Ignition harness.

PLEASE NOTE****** The picture posted is of 2003. Recent 2005 Viper 791xv Wiring is actually different in Order of Color for the Secondary Harness H2.

H2/1 Light Blue (-) 200ma 2nd Unlock Output ~~~ Can be removed and Depinned?

H2/2 White/Black 200mA (-) programable channel 5 output = Can be removed?

H2/3 Violet/Black 200mA (-) programable Channel 4 output = Same as above

H2/4 Green/White (-) Factorty Alarm rearm = can be removed and depinned.

H2/5 Grey/Black Diesel wait to start bulb = Not needed we dont have diesels

H2/6 Green/Black Factory disarm = We dont have alarms.

Since the SE has power locks do we use the Door Lock harness Blue and Green?

So Harness H2 can be deleted correct?
