Wire harness thru firewall ideas ?? - Lateral-g Forums

Here are the PCM pinouts for my 2002 LS1 PCM from a vette. 2 connectors with 80 slots each - but many aren't used.

I don't have a harness yet - so I left the gauge column open for later. I asterisked the items I felt should be in the bulkhead connectors. Looks like we could easily get 2 bulkhead connectors with enough capacity - even if we break them into power/servo and sensor.

Excellent! Ok, I think if one or two bulkhead connectors were identified and a source for them, all could use them as they choose. Maybe three would be the way to go, since some may want to use only one total bulkhead for all the leads. I think a 48-pin for a total would work, but would have to look again to be sure.

I looked at some of the connectors yesterday, there were ones that were waterproof, and oil/fuel proof that had enough pins.

How about these weatherpack bulkheads?

I like this one, but is enough pins?

Nope, would probably have to do 3 of them, and don't think they're RF insulated within the connector....

OK, why do you need RF shielding within the connector if all the rest of the cable in the harness is not RF shielded? I don't think this is necessary and it doesn't gain you anything.

Some do have shielding, and there's also a dependance on the resistance of the conductor as well. I don't recall off the top of my head which, but once I revisit this area I can post. I just kept a mental note that it was required, though it's possible I could be wrong on that. Certainly two I know of are crank & cam sensors. Guess that might be only an issue if you mount the CD box inside...
