    Not quite sure what you mean by "CROSS REFERENCE", but by your location/connector arrangement description I'd say it's the AC ECU. What's the "...PROBLEM I HAVE BEEN LOOKING FOR."?

    MY CAR INTERMITLY DIES, I TRACKED IT DOWN TO A ELECTRICAL PROBLEM. I FOUND INSIDE THIS RELAY A BAD SPOT ON THE PRINTED CIRCUIT BOARD I MADE A TEMPORY REPAIR . THE CAR RAN FOR ABOIUT 10 MINIUTS THEN DIED MY TEMP REPAIR BROKE. THEIR WAS ALSO A BROKEN TRANSTOR. THIS PROBLEM HAS BEEN GOING ON FOR 9 MOUNTHS. I CHANGE THE FUSE PANEL, 2 WATER SENDING UNITS, COIL MODUALS, CLEANED ALL ELECTRICAL CONECTION, IN STALLED DIE ELECTRIC GREASE, I EVEN REMOVED THE DASH AND KEY ASSEMBLY TO LOOK FOR POSSIBLE SHORTS. THAT WAS NOT AN EASY THING TO DO.THIS RELAY DOES SOMETHING WHEN I FIRST TURN ON THE KEY.

    Unfortunately, I can empathize with your frustration having been on a couple of long TR electrical gremlin hunts myself. I'm fairly familiar with the TR wiring diagram book, and would be glad to see how/if the AC ECU wiring could interact with the things (injection/ignition) needed to keep the engine running. There might be some places you could make some voltage checks if you're comfortable with that. What year/version is your TR?

    OK THE REALY IN QUESTION HAS NOTHING TO DO WITH THE RUNNING OF THE CAR. THE CAR STARTED UP TODAY WITH THE RELAY OUT OF THE CAR IM GOING TO CHECK SPARK AND FULE PRESSER NOW.THE CAR IS A LOT MORE FUN WHEN ITS ON THE ROAD.
