Starter Issue, Starter does not respond to ignition switch Options

[downrange]

Restoring 1974 914 1.8 liter L Jetronic. No starter response to ignition switch. Replaced original starter - no luck. Installed Bosch Starter Relay Hot Start Kit - No luck. Cleaned ground connections to transmission ground strap - no luck. Any suggestions?

If not obvious, I am like a monkey with a iPhone when it comes to auto electronics.

A 74? Look under the passenger's seat. There is probably a box plugged in under there with "LOGIC RELAIS" on it. That is the Dreaded Seatbelt Interlock Relay.

Unplug it, and give it the "float test". (Throw it into the lake; if it floats then save it for further study.) Then plug the two large yellow or yellow/red wires that go to the socket together.

If the starter then works, remove the temporary plug and permanently attach the two wires together. Either a butt splice or solder them and cover with at least one layer of shrink tubing.

The Seatbelt Interlock was disabled many years ago.
