Thanks Jethro, Craig.
I have started to do some work on the electric headlight conversion. The Mazda motors are fitted to a bracket that then bolts in place of the vacuum actuator.
From what I have read on US forums this tends to flex quite a bit. I decided to use what some of the members suggested and use two brackets per motor.
I made up two 1 7/8" long spacers and bolted it all together with a 4" 1/4x20 bolts and nylocs.
The brackets bolt to the four existing holes from the vacuum actuator. The link rod and heim joints then fit to the existing actuator linkage pin.
I will run the main power from the alternator to a relay and get the trigger from a wire run to the dimmer switch.
While I am at it I will fit another two relays for the low and high beams. This way I will get full power to the lights. The existing low/high beam wiring will be used to trigger the relays.
I am still looking at ways to convert the wiper door to electric. One way I have been thinking about is using a small 50mm stroke linear actuator and making a bracket that fits where the existing vacuum actuator is. I am still working on this
