Default '99 3800SC-V6 PCM Pinouts

Need the PCM Pinout locations ad Descriptions (Wire Colors would be nice to). Trying to resurrect Frankenstein again. Brain Dead is just the start. Need to find his fingers and Toes. Most are detached do to childish stupidity (not me either).

How many threads are you going to have about pinouts on various things?

You will want to be more specific on the donor vehicle for your swap. As mentioned in your other thread, I've got all the manuals and can help....I won't play guessing games on what vehicle it came from in case the pinouts are different.

Until you help us to help you, I'm going to wait and not give you Bonne schemaitcs if you need Park Ave and they could be different by one or two pins that will cause us to spend a ton more time.

Donor was a '99 SSEi according to the Salvage Yard. I don't have a VIN Number but wish I did now. Can I get any other number for a reference to help ?

Only if you knew the production date. Currently you don't though.

The VIN will be able to be seen once you have power and a DLC connector.

I'll grab that 99 pinout for you tonight.

I don't know if this will help. I ran home at lunch and got the Numbers off of the PCM itself.

PCM Numbers:
SERV. NO. 09361735 BWUM
86BWUMM28239713H

HDW. NO. 09357440 BWUM
86BWUMM28239713H

Alternator Numbers:
10480348 110 A
8239C0 C20 N (not sure about the 8239C0, too hard to read)
