Will a 67 X underhood wiring harness fit a 69 runner ?

Think I found a nice one and it looks like it's pretty close looking to the 69. Heck, the one on my 66 looks similar except it's for a /6....

There are differences between A/C and NON A/C. The blower motor wiring is under the dash in heater/defroster cars. Otherwise, the wire paths are the same. The terminals may be different.

It Could work. Going to need to look at the wiring diagram for each car. You can move terminals in the plastic. Connector if you need to. All the circuits should be same or similar. So just get them in the right place at the connectors.

differences are the neutral safety switch and backup lamp switches.

Also a difference between Big Block and Small Block because of distributor location. Minor length difference but there .

Its easy to wire

A 1967 engine wire harness has the coil wire come out in the middle of the engine and you route it front or rear for BB or SB engine. Not any issue there.

67 X as in GTX and 69 runner as in road runner Both are big block wedges....just RB to a B engine and doubt there's much difference if any in the wiring between the two....
