67-70 TH400 Kickdown Harness Firewall Hole Location

[pjmoreland]

Does anyone have a photo that shows the stock location on the firewall where the TH400 kickdown harness passes through on a 67-70 truck?

My '68 has a TH400 that the PO installed, but he did not install a kickdown switch. I've purchased a 67-70 kickdown harness from GMCPauls, along with a B&M switch that I will mount to the TH350-style kickdown bracket currently on my engine. I will have to drill a hole in the firewall, and I'd like to put it in the stock location.

I searched through many threads about TH400 kickdown switches, and the closest I came to a photo was in this post, although it was a bit vague.
