1974 Dodge Dart Sport rebuild

Builderguy said

I know why they came up with this (trying to avoid installing air bags) but it was subject to so much failure that it was quickly bypassed. Like one of the PO's did. Now I have to remove his/her modifications, removing the blue jumper wires and toggle switch, and installing another bypass that is not seen and that does not require any user input. My understanding is that this safety belt interlock was only used in 1974. Fun to be had by all! Almost forgot, Happy Easter!

Here is my suggestion to bypass the interlock and make it invisible:

There should be 2 yellow wires in the bulkhead connectors. Swap those 2 and the start signal will go to the starter relay instead of the interlock circuit board. Shouldn't matter which side of the firewall you make the change on, but I would suggest the passenger compartment side just because it will be harder to tell.

The other option is to leave the seat belt's unplugged.

Let me know if you want wire locations on the bulkhead and I will dig them out.

Great build, impressive work.
