Bill, do you have a 1972 Pontiac Service manual?
This should be similar 2 wire swap deal as used to convert '68, 69-early '72 A-bodies from idiot light harness to Rally gauge harness.

I'll ck out my '72 Pontiac Service manual this weekend & post back.

Unfortunately I do not see the wire for the seat belt lamp. And looking at the Ames catalog shows 2 different circuit boards - the harness contact pads seem to be different too.

No, unfortunately I let it go with the sale of my last 72. I have a wiring diagram but like what Scarebird's post shows it only covers the 69-early 72 wiring.

This may help. Ames has pix of both their printed circuits. I put them both in one pic, then traced the circuits. I would check - it is 3am here and may not be accurate.
