I finally figured out a neat clean way to make a kit available to convert your wiper door from vacuum to electric. The best part is the kit uses the same technology as my Killer Light vacuum to electric headlight conversion.
You will need:
1. A Killer Wiper Bracket kit
2. A left hand 1997 style Firebird headlight motor
3. A 1997 Firebird style control module.
4. Factory wire harness pig tails, or aftermarket generic (to connect to the module).
5. 1/4x20 tap and appropriate drill.
6. Spot welder
First remove the vacuum actuator and bracket. Next, locate the Killer Wiper door bracket on the firewall and mark the two mounting holes. Drill and tap these holes (this will go into the wiper door support on the other side of the firewall.
Next, you will cut the stock firebird arm down and spot weld the new 5/16x18 stud on the end.
Mount the actuator on the bracket and adjust the arm as needed by rotating the stock C3 wiper door adjustment sleeve.
Find a good spot for the module. I suggest in the back of the passenger fender well. You will run a battery and ground to the module. You will tap off the power wire that goes down into the wiper motor to get the up signal. You will ground the down signal on the module.
Plug it all on and watch it work!
When you turn the wiper on the wiper sends power to the lower part of the wiper motor. However, it won't run until the limit switch on the firewall makes a ground contact. The signal going to the wiper motor excites the module and causes the wiper door to lift. Once lifted the wiper motor will start running. When the wipers are turned off the power doesn't drop off the lower part of the motor until it goes to full park. Once that power signal drops off the module it will close.
How simple is that? Pretty cool...huh?
Week after next I will start packaging and offering the bracket and hardware shipped for $50. You will need to supply the actuator, module, wire connectors, and bulk wiring.
Here is an idea of what it looks like:
