Cut to the chase..... …..…..In looking at the new switch bottom side, with lock tabs on the bottom, the two smaller spades are top, and middle, and the bottom spade is larger. On the Ford OE pigtail switch I’m replacing, this has the same female plug-ins as my NEW SWITCH, so even though the harness wire coming off the pig-tail harness has that BIG FAT STRIPED WIRE going into the Middle hole, does this only mean this spade gets more power to this smaller middle tab, and NOT to the larger tab on the bottom? My NEW pig-tail switch has the larger BIG FAT STRIPED WIRE coming out of the bottom female connector. Some say match exactly to what’s already there…wire to wire, and others say to match the big fat wire to that other big fat wire, that’s why as much time this has all taken, I am getting pretty confused for something that seems so simple! I’d hate very much to cross wire and cause additional problems. ____________________________________________________ I ordered a pig tail female connector for the switch which is either for the fuel pump, or the other relay, maybe the computer relay (the corroded looking switch pictured above) this original 4 wire pig tail, the TOP of this switch has numbers like this.... FORD'S NUMBERS are # E93B 2C013 BUT...... I need the FEMALE counterpart with Pig tails. (1) The Fuel pump relay switch. I have no idea which is which. (2) The EEC, or ECC relay switch.....Computer relay? (3) Blower fan switch, does not work anymore, had a fire in the blower box. OK. I thought I was already to GO! I bought a fuel replay female 4-wire pig tail (or maybe it’s just a electrical connector from Pep Boys # PT5685) Looking at this NEW box relay with the lock tabs on the bottom, The NEW wire configuration has this- On the right side, there are three wires coming down, Top right - solid BROWN, Middle Bottom -solid Red. Bottom – bigger orange with Stripe green and Left bottom - One YELLOW (going opposite direction than the other three) The OLD wire configuration has this- Top right - solid Black Middle - Fat Red with Green Stripe Bottom - solid Red. and Left bottom - One YELLOW (going opposite direction than the other three) Question? Do I match old wire locations with new wire locations, switch to switch, or do I match the fatter, bigger striped wire with the same, even though they are not in the same location on the switch? Another (silly and maybe stupid question) which switch is which? Both relay switches look the same, but one is for the fuel pump relay, and the other i think is for a computer ECC, or EEC relay. (fender well pass. side near the idle control valve on the air filter) which relay is the fuel filter, and the other is the ECC or EEC relay? They both seem to have only four spade males, three going one direction, and the fourth going the other. The UNKNOWN SWITCH IN THE PHOTO, IS MY BLOWER FAN MOTOR. Sorry. I did a Google, and put those FORD numbers in, and found many with -AB, -AA, -BB at the very end. Is there a Ford cross reference website to after market electrical connectors, or anything else Ford to buy aftermarkert? Thank you for any and all replies! Happy Weekend!
