[DeTomaso] Blower motor replacement

[Kirby Schrader]

Brian,

Just go to eBay and do a search for pulse width modulator. There are many
available at almost any price range you'd like.
If you want the exact model I used on the GT40, I'll need to go home and
look it up. It's been awhile, but it kinda' looks like this one...

You have to unsolder the potentiometer from the board, install the
potentiometer into the dash and then run wires accordingly.

Regards,
Kirby
