how to make an LLY bench harness?

[Trippin]

88953346 connector should work for the both LB7and LLY ECM? :?

I tried to get the part number from the dealer and had no luck. If this will work this will be great.

The LB7 and LLY are different ECM connectors. Same TCM connectors.
TCM Grey connector part # 15305371

Trippin,

Do you have the pinouts for the LB7 ECM?

Not sure if this is correct pinout.

Pin 19 = Ign
Pin 20 = 12v
Pin 58 = Data
Pin 60 = Gnd

I'll post them tonight when I get home as well.

If you have the LB7 ECM connector can you post that to?

Does anybody know is this is the same blue connector needed for a LS1 bench harness?

Thanks

LB7

I purchased a very nice premade harness. Near as I can figure these are the designations.

Blue connector

Pin #1 and #40------------------Ground
Pin#20 and Pin #57---------------Batt
Pin#19---------------------------Ign
Pin#58---------------------------Serial

Revised Pins 19,20 and 57 based on my GM service manual.

LS1 uses the same connector as LB7. Part# 12191488

Is that the GM part #? Just checked GM parts direct and 12191488 was no found.

That's the number from my GM service manual.

Looks like it's Delphi.

I'm new here but I've read that a few of you have gone to salvage yards to get conenctors, go to Delphi's distributor for connectors. Power & Signal.

Their policy is that they can mail up to 25 samples per order, that is if your a company? You can also purchase crimpers, terminals, seals.......

Hope this helps.
