 For those who moved their PCM inside, how, did you seal the hole in the firewall? |

I cut a hole big enough to slide the pcm connectors through.
But there is no grommet big enough (that I can find) to seal it up. Did you make some kind of 2-piece cover plate to go over the hole? Fill it with putty? Some other solution? (it took a pretty good size hole to get a pcm connector (and the wire bundle on top of the connector) to go through) Maybe everybody else just pushed all the small stuff through from the inside of the car, instead of pushing the big stuff through from the engine bay side...? |

Good advice from all - the only thing I can add is that I would run the high current stuff - starter/alt/bat+ thru a separate passthru. If you have a short and melt a big wire you don't want it to take out the PCM harness too.

If you have a short and melt a big wire you don't want it to take out the PCM harness too. Good point. It didn't seem quite right to have them all together, but I couldn't come up with any good reason to separate them. That's a real good reason. |
