Harness pass thru hole size

[waynieZ]

Hi What size hole did you use to get the main harness for your LS ECU through the fire wall?

speartech grommet. Just matched a hole saw with that size.

T,

Thanks guys

I was excited that we're getting close to wiring the motor then pulled the harness out of the box. Whole crap load of wiring. I'm just hoping there is not too much extra length in the main harness. I don't want to start cutting it up to shorten it.

Randy, that's the exact one I was looking at this morning. I called and they're closed for the holiday. I tried to find some where else that carried them but nothing showed up.

I'm going to come through the hole in the floor for the gas pedal linkage. My buddy has punches for electrical boxes so we'll use that to open it up.

Not sure if it'd be quicker here, but try this:

That has to be installed on the harness during the building of harness, unless you "cut/ split them" length wise, but they dont seat or seal well sometimes when you do that

be cautious as to how close that will place the trunk of harness near the #7 header tube

You are going to mount the ECM in cabin I take it ?? I mounted my ECM by the battery tray/fender. Only wires going through the firewall are for the DBW pedal and OBD port. Harness runs through inner passenger fender (out of sight)

DT69Cam I have the inter cooler reservoir there, only enough room for the AC and heater hoses to go up by it .
The header is not a problem the hole for the pedal is behind the head almost where the head meets the intake so there's plenty a room.
