I am installing this alarm in my ranger and have run into a problem/question. The information I have says that you can use pin 48 tan / YELLOW wire and well, I found pin 48 but it isn't tan / YELLOW and when I tested it I didn't get anything from it in the way of showing change in rpm. Now anyone know of a different location or do I really need the tach connected?

TIA
Brian

how did u test it? U must set multimeter is the AC voltage side and put black to ground. Tach will give u a much cleaner start.

The PCM (Powertrain Control Module) is on the top of the firewall under the hood towards the passenger side. The tachometer wire is in pin 48. Can also get tach at the ignition coil or coil pack. Use any of the tan/stripe wires.

Where theres is a wire there's a way.

you can also go to the odd colored wire at any fuel injector

Hey, I found the wire off the pcm. I have to untape the wires more and it was right there. The remote start works great. I do have a question though for the locks. The alarm supports 2 door unlocks, one primary for the drivers and secondary for the passenger. Now I know I can find the wires to unlock them both at the same time but I want to unlock them seperately. Also, what is the easiest way to wake up the GEM? I was told I could use the latch wire off one of the doors to do this and not need any diodes. Anyone else hear of this?

TIA
