Remote start 93 trans am

I am installing a remote start on a 93 pontiac trans am. I can't get my start system to recognize the constant power ignition wire based on the diagnostic code I'm getting from the parking lights flashing. Is there two on this vehicle or am I missing something? Also, which wire on the coil will work for the tach signal?

Ok, vehicle starts, runs, cuts off, everything but the starter keep turning longer than it needs to. It acts like it is not picking up the tach signal. I have it hooked to the white wire on the coil. Also, it still does not act like it is hooked up to the proper ignition wire. There are two pink wires in the ignition harness, both have 12 volts during run and crank. I guess it has 2 ignition wires. I have tried hooking into both and neither one fixes it.

nevermind...got it working.   Thanks for your help.

One more question. I am having a lot of trouble with the locks. I have found the RED / black and the ORANGE / black wires coming out of the keyless entry box on the passenger side. I have hooked into these wires and have used a separate power source to the relay and cant get anything. Do i need to use the dk blue and lt blue wires that go to the switch or how do I go about this. I cant find much on these 5 wire locks, but i have found plenty on the 3 wire locks. How do I do these?

I'm having trouble with the locks on a 93 Pontiac trans am. I hooked a relay with separate 12 volt power into the wire after the switch to bypass the BCM. The locks worked great for severla locks and unlocks, so I began putting the car back together. During the reassembly, I decided to try them again. Now, they will lock great using the new alarm remote, the factory remote, and both switches. The problem is with the unlock. I hooked into the driver's side wires coming out of the switch. Now, the passenger switch and the factory remote will unlock the doors, but it is extremely slow, sometimes taking two or three pushes of the button. Acted like a thermister, but let it cool and did no better.   The new alarm remote will not unlock them at all, even though it is giving them power. The driver side switch will not unlock the doors, but it will lock them. I dont know what to do now. Please help.

I wanted to add this to my post. When using the factory remote, the passenger side locks even when I push unlock. I must have a short somewhere. Anyone got any ideas?

I have taken the factory keyless entry box out and put jumpers from the orange and black to the tan wires and from the red and black to the gray wire. It does exactly the same thing as with the box connected. It acts like there is not enough amperage to power the unlocks. The driver actuator is getting 12 volts but does nothing on unlock. The switch is good. The actuator is good, I used wires from the battery and the actuator works. Any ideas?

I installed a remote start on my 93 trans am. When i turn the car off with the key, the radio stays on until i open the door as it should. Then, when i open the door, the radio and clock stay on (the clock is part of the radio), then the clock turns off, then a couple of seconds later, the radio turns off. What would cause this?

you powered up the brown accy wire didnt you?  that controls the circuit the radio is on (assuming that year has it).  if you just want your heater to run then use the orange accy wire only.  you shouldnt have to use both unless you want the radio on.  if it is staying on after you open the door then its probably getting some power backfeeding to it from the accy circuit.  i cant say this for sure because i havent had it happen to me, just an idea.

Yes, i did hook into the brown wire. I cant find an orange, i have two pinks comin out of the ignition wire harness. they are both hot during run and start.

be careful if you do not power up the third ign wire the trans will not shift out of first on many gm vehicles

I am just curious, but what exactly do the 2nd and 3rd ignition wires do. Do they power the accessories or what?

I varies on the car. I know for example that on some gm trucks you must catch the white 3rd ignition wire or the transmission won't operate correctly.

yes that is what they do....they power up other things in the car or truck.....tranny....blower motor......some cars wont run unless they are powered up......

I have an Ultrastart 2256M installed on my 93 Pontiac Trans Am. The lock and start features work great. Both the lock and unlock outputs are supposed to be negative. The lock is, but the unlock is not. It is actually putting out a small amount of positive voltage somewhere around 4.8 volts at the unlock pin for the plug on the box. Also, when the unlock is activated, there is no continuity to ground as I would expect there to be since it is a negative output. Is this a faulty remote start module or should I tear into it and try to figure out why it is not functioning properly. I am having trouble getting the person I bought it from or UltraStart to cooperate with me. What should I do?

i have had no prob from ultra start....did you check the lock wire to see if it is the same way???

Yes, I checked the lock wire. It is negative. Also, the locks work when I hook them up to the trunk output, which is also negative. I think something is messed up inside the remote start module.
