Wiper Motor Control

I have decided to replace the Infinity wiring system with a more typical "Hot Rod" wiring system from Ron Francis Wiring. I am in the process of installing the system and realized that the Infinity System had built in controller for the windshield wiper motor. Does anyone have any suggestions on the type of controller I need to go between the wiper power feed to the wiper motor that supplied with the GT-R or SLC?

There are many simple DC motor speed controllers. Most are very inexpensive but a project like this make take some trial and error and a few binned pieces. Here are a few I found that I think just might work and are very inexpensive.

It would help to know how much current your motor draws. Maybe try and find out what it was fused for in it's original application and go from there. Or if you don't want to experiment then:

The standard wiper motor is indeed a marine setup. It has two speeds, and no delay- as is typical for any motor. Any delay logic is part of the harness. The default harness never had a delay function (for either the SLC or GTR), so adding it would be something you'd have to do on your own. This is normal, and you'll find that aftermarket harnesses don't have provision for a delay function on the wiper motor either.

The RioRand listed in Howard's post. It has a built in fuse and is not bothered by a polarity error. I know very little about them, but it seemed the safest for a novice car electrician.

If you still require a solution, send me a message.

I can build you a custom controller for the wiper motor. It can be a simple as a black box, or as elaborate as a touch screen
with graphical user interface.

Tino, Can this feature be built into the gauge system software?

Hey Roger,

You are correct, it can all be bundled together with the LCD software.

Going further, it can be built as a stand-alone console screen controller for those wanting to keep their dash configuration intact.

It's a fairly versatile module - it can also hide behind the dash and do automatic functions like fan control, lighting, etc.
