help identifying LS1 harness connectors

**nath** · 11-07-2009, 05:21 AM

I have searched and searched with no luck. With the harness in my lap and looking at the LS1 wiring skematic how do I identify the connectors by the numbering in the skematic?
Attached pic of an example.
I have the pin out sheet and can follow that but I can't identify the various connectors except the obvious ones like FI and coills.

Well, I don't seem able to attach files so no pic.

Thanks for your input.

If you can't upload your picture here, try uploading it to tinypic.com & posting the link. That will give us an idea of what you're looking at.

If you're looking at the factory service manual for your car, I'd recommend obtaining a Haynes Repair manual (#24017). The wiring diagrams are a bit easier to understand in a Haynes, since it just lists wire colors and components.

I have not looked closely at the connectors on our car as of yet. If I recall, other vehicles I have had apart sometimes have the connectors numbered. The easiest thing to do is match up the color code of the wiring to the schematic to ensure that you have the correct one. To be double sure, locate another wire on the schematic in the same general area and compare numbers to colors to see if it corresponds.

How do you know this? I am an electrical contractor and pretty good at wiring diagrams. Perhaps I need a vehicle shop manual to identify the connectors.

Thanks for your help

Oh, I forgot one tiny detail. I putting my LS1 in to a 3rd gen RX7, not a fbody.

Then you don't need that connector anyway.

Leave only what is DIRECTLY related to engine control.

I have access to a lot of stuff cause of where I work. But most vehicle shop manuals will give a key for the connector locations and what now. Finding it could be a task but they are there. hopefully the images I posted will help you with the other connectors.
