Cool, I'll give that a shot, thanks.

@Airborne Janitor, thanks a TON for the step-by-step! My brother @jamespwsullivan just installed a '99 motor. We added a ground wire and re-bushed the linkage. We found that Weather Pack makes a nice round 5-pin M/F shell pair so we installed those to keep the connections dry.

 

Via bench testing, we found that the '87 reman motor (almost 0 miles since install) and the '99 motor operated at about the same speed on Low but the '99 was definitely faster (more wipes per minute) on High.

Glad it helped! For anyone reading I have a 2000 XJ motor with the renix plug already soldered on for sale. All you gotta do is bolt it in!

I just finished flushing the old grease from my wiper motor gearbox, added new grease and a separate ground. The performance is identical to before the work. I have the non intermittent wiper stalk.

 

Does anyone know if the gearbox gear ratios changed on the new gearbox vs old?

Seems like I wasted 2hrs and should have just purchased a 97+ motor.

I just followed this guide. old motor was taking 3.3a while on low setting. New motor consumed 1.2a while on low setting. I think I either repacked too much grease in the old motor or the fat lady was singing and I gave her the microphone

Chiming in here to confirm that using the newly manufactured wai motor was leaps and bounds better than the stock motor + regeasing. My old wiper motor was squealing bad. You can hear it in the below video. It may have lived another life if I completely rebuilt it, replaced the brushes etc...
But I think this was the more reasonable solution.

Oh, the newly manufactured motor was also dimensionally compatible with the old one and fit in the stock rubber boot.
