Getting thru the firewall

[woodmaster58]

Hi Everyone

I've just installed a transmission temp gauge and want to put the sensor head in the rubber lines near the radistor
I have to penetrate the firewall...how do I do that and where?
thanks

If it's an automatic, you can go through the clutch master cylinder block off plate.

Does this help?

This grommet is below the ABS tray next to the brake booster.

I recently moved all my accessory wiring to a hole behind the glove box.

Hopefully, those wires have been cleaned up since this photo. Also, there are a couple of connectors missing on your PCM

That was mid transmission swap, mid wire move.
