Wire harness thru firewall ideas ??

[HWYSTR455]

Garage Dog 65 - I'll take you up on that! I have a complete pinout of the FAST XFi box, and have done considerable amount of background on that. I know that a number of the leads in my case will not be used, and personally, I would prefer to use the smallest connector needed. REGARDLESS, I would be happy to use one that accounts for all the leads, just out of convenience.

The best scenario would be to use a 'mixed' connector, that accounts for the correct number of leads for the correct gauge wire. THAT will take going down the schematic and counting the gauge/pin/lead thing and recording. Not particularly difficult, just needs to be done. It may not be feasible to do in one connector.

As for which ECU, let me say this. All have a basic number of required sensors and drivers, correct? Like TPS, Water, IAC, ATS, Crank trigger, Cam trigger, etc. One could account for these and create a pass-through config that would generally account for most, if not all ECUs. One's that require more, like trans or whatever, could use an additional bulkhead. Just a thought...

When I get home I'll post the pinout on the FAST. Garage Dog 65, I'll be more than willing to help in any way I can, though I'm sure some have already done what we're talking about, would be nice if they anti-up, wouldn't it?
