THANKS FOR THE VERY FAST REPLY, ONE OF THE FOBS ACTUALLY WORKED ONCE TONITE, AND IT STARTED SWEET AS, BUT I SWITCHED OFF, WENT INSIDE, CAME OUT AND ZILCH AGAIN, ALSO CANT FATHOM THE GROUNDING WIRE NOT WORKING, I GROUNDED IT DIRECT TO THE NEG TERM ON THE BATTERY?????

Are you sure you grounded the right wire, I am not exactly sure about your ZJ but on my 94 ZJ, there are 3 or 4 PURPLE/YELLOW wires in this group of wires (behind Driverside kick panel). I know this because when I installed my remote starter/keyless entry/alarm on my ZJ a few months back. I had a problem with it working, so I went back an looked at the wires again and I found another PURPLE/YELLOW wire, switched it with the one I had it hooked to and still nothing. In the end I found a total of 3 or 4 of these wires, all the same color, before I finally found the right one.

I COULD ONLY SEE THE ONE, BUT CONDITIONS WERN`T IDEAL, BRIGHT SUN I MY EYES ETC, I GUESS I`LL HAVE ANOTHER GO TOMORROW SO UNUSUAL FOR HER TO LET ME DOWN, SO RELIABLE NORMALLY, I OFTEN HAVE TO MOVE ONE OF MY 5 TONNERS, ONE EVEN WITH THE DIFF SEIZED ON A HILL, SHE LUGGED IT TO THE SIDE WITHOUT A HICCUP.
AS I SAY I`LL HAVE ANOTHER TINKER TOMORROW, THANX AGAIN FOR THE QUICK REPLIES, LES.

BY THE WAY, IS REPROGGING THE FOBS A DEALERSHIP JOB?

[dksob81]

Yes, you will have to take it to the dealership to get it reprogrammed, On older ZJ (95 and earlier) you could program the yourself.

JUMPED STRAIGHT TO DOOR HARNESS, FOUND 1 PURPLE/YELLOW, GROUNDED IT, BUT STILL NO JOY..........AHEM!??

THE ALARM/IMMOBILISER WONT RESPOND TO THE KEY LOCKS EITHER!

[dksob81]

What exactly are you trying to do to the PURPLE/YELLOW wire?

ACCORDING TO THE WIRING DIAGRAM THE PURPLE/YELLOW (IT ACTUALLY SAYS VT/YL, WHICH I PRESUME IS VIOLET/YELLOW) WIRE SHOULD BE GROUNDED TO EARTH TO DEACTIVATE THE ALARM, THIS I`VE TRIED AT A COUPLE OF POINTS, AND IT DOES NOTHING.
I`M A CAR, TRUCK, HEAVY PLANT & MACHINERY MECHANIC (NOT FITTER, I TRY TO REPAIR RATHER THAN FIT NEW, A DYING BREED), BUT WHEN IT COMES TO MODERN VEHICLE ELECTRONICS, FORGET IT, THEIR A PAIN THE ASS!

[dksob81]

Yes, VT/YL means Violet/Purple.

Check, recheck and heck check again, the wiring group in the driverside kick panel, I know for a fact that there are more then one VIOLET/YELLOW wires here, you might be trying to ground the wrong wire.

YES, I THOUGHT JUMPING STRAIGHT TO THE ONE IN THE DOOR WOULD SAVE THE HASSLE OF SORTING THEM OUT IN THE DRIVERS FOOTWELL, IT`S P***ING DOWN WITH RAIN AT THE MOMENT, I`LL HAVE TO DELVE FURTHER WHEN IT STOPS.

TRY, TRY AGAIN...

NO, NO BROKEN OR DODGY LOOKING WIRES OR CONNECTIONS, ALL IS IN A1 CONDITION, ALL CLEAN AND DRY. CHECKED VOLTAGE & GROUNDING CONTINUITY IN AS MANY POINTS AS POSSIBLE, ALL SEEMS OK....
SO I DONT KNOW, IT`LL PROBABLY GO AGAIN WHEN I`M WAY OUT ON THE ROAD SOMEWHERE AT 3.00 AM IN THE MORNING, SODS LAW!
THANX FOR YOUR HELP BTW!

Just A Tip For Some When Checking Wires In A Circuit, If You Dont Like To Cut Wires Or Strip The Sheathing Down To The Core, Just Stick A Pin, Small Nail Or Sharp Probe Thru` The Outer Sheathing And Theres Your Check Point For Grounding Or Checking For Power, Leaving Minimal Damage!!!!!
