Yesterday, a friend and I attempted to install a CompuStar 2WSS-AS (Alarm + Remote Start) into my 1991 Nissan 240SX SE with Manual Transmission. My 240SX has an sr20DET (Turbo'd) motor, so I have a different ECU, a turbo timer, a boost controller, and an S-AFC (modifies air/fuel ratio). The wiring differences between my car and a normal 240SX are only in the engine bay, and by the ECU. Pretty much everything under the dash is stock, so standard wiring diagrams have proven to be accurate.
Anyway, we wanted to first get the alarm and door lock/unlock before messing with the remote start. Looking at the diagram below (which I know is for a suburban, but I just copy and pasted that from a different post. The first 3 columns are the important ones), we wired the first set of 8 pins.
On the second set, we wired Pin #1, but we didn't know where to connect Pin #2 (Status). The description says that it comes on one second before ignition on and turns off one second after ignition off, but that didn't help much. I don't need Pins #3 & #4, and Pin #5, I haven't wired, but I will. I figured I didn't need that for the alarm to work.
For the 3rd set, we wired Pins 1,3,5,6,9. I didn't install the included Hood Pin sensor yet, so we'll do Pin 2 later. We couldn't find the trunk input near the dash, so we'll have to run a wire to the trunk for Pin 4. I don't have a diesel so Pins 7 & 8 were ignored.
4th set: I think we only wired Pins 4-6 (We had to use an extra relay, because my Nissan uses a single wire lock/unlock system.)
5th set: Pins 1,2,4.

Questions:
1) Where does the Status Pin go?
2) Is the LED supposed to be lit constantly? When we first wired it, it was always on, but by the time we stopped, it would only flash when I connect/disconnect the car's battery.
3) When we did the on/off 5 times thing to put the computer in "Learning Mode" nothing ever happened. No relay clicking sound. And, after putting the battery in the remote, it would be silent for about 15 sec, and then emit 3 (not 2 like the instructions) beeps. Remote still doesn't work.
4) Will we were zip tying some wires together so I could actually drive home, the alarm brain suddenly made several clicking sounds completely out of the blue. Does someone have any idea that would happen?
5) Can anyone give some pointers on what to do w/ the included 2 relays that I'm supposed to used for the starter and second starter? It looked pretty confusing.
I'd appreciate any help you could give w/ respect to these questions. If you need clarification, please let me know.
Thanks,
Ruban
