1992 jeep cherokee, remote starter

I am trying to install an UltraStart G11TL remote starter / keyless entry system in a 1992 Jeep Cherokee and am having problems.  I have everything hooked up as per the manual but I can't get the thing to work.  I keep getting 7 blinks which means tach lock-out.  I tried programming the unit to work in tachless mode and still can't get it to work.  No matter what I do I get 7 blinks.  Also, when I press the lock button I get one blink but the locks don't lock.  When I press the unlock button I get two blinks but the locks don't unlock.

The only problems I can think of are as follows:

The 92 Jeep wiring diagram says that the starter wire in the ignition harness should be YELLOW /GREEN and I could only find a solid yellow.  That is what I used.

I am not sure if this Jeep has a factory alarm system.  There is a little black "eye" on the roof near the domelight but I have no way of knowing if there is an alarm.  I have had the jeep for a long time never thought it had one.  Maybe I just never had the remote for it.  If there is an alarm how would I disarm it??

I used the wires in the ignition harness......the wires in the harness were red, yellow, blue, purple, and orange.   I connected both 12v inputs to the red, the acc to the purple, the ignition output to the blue, and the starter wire to the yellow.  I did not use  the orange wire for anything.   

I did use the ORANGE / purple and pink/purple in the drivers kick panel for lock and unlock.

The wires from the remote starter unit that i did NOT use were the following:

Selectable Output (white), Diesel Wait To  Start Input (blue),  Horn Output Optional (WHITE/ blue),  Hood Pin Switch Input (GREEN / WHITE), Re-arm output (yellow), Trunk Release Output (RED / white), Dis-arm Output (Brown), Starter Kill (Orange), and Ground While Running Output (WHITE/ violet).

I did NOT use any of these wires for anything.  Could this be my problem?
