Wiper motor 64 E-type. Wiring harness to motor color code has become indistinguishable. I am connecting a new body harness. Can anyone tell me where which color code connects where, inside the motor?

Linda,
Here's a diagram which worked OK for me. The motor isn't too complicated if you've ever tackled any sort of DC motor before.

Good luck,
Dick

Linda: Your question states "inside the motor". Well, there is a bundle of wires coming out of the motor (as you know), but specifically inside the motor, I don't think you want to go there. As I recall, the wires coming out of the motor have a short distance of sheathing around the wires. Is it possible to carefully cut-away about a half-inch of this sheathing to see correct colors on the wires?

If not, is the motor free of the gearing; can you hold it in your hand or put it on a bench? If so, I would give serious consideration to having that motor rebuilt, including the replacement of the pigtail wires coming out of it. It serves a fairly important function, and you would hate to have your wipers stop because you didn't take care of the motor when you could have.

Looking at my handy dandy wiring booklet for 1964-1968 E-Types, you should have Green, White, Red, Yellow, Blue, and Brown wires exiting the motor. The Green goes to the Fuse Block. The White connects to a White/Lt. Green wire that goes to position 5 on the wiper switch. The Red connects to a Red/Lt. Green wire that goes to position 3 on the wiper switch. There is a second Red/Lt. Green wire that goes to the screen wiper park switch. This switch is very fragile and mounts on the 3 wiper actuating arms, and it's a bitch to get to. There should be a little knurled knob on the firewall that adjusts this park switch. By all means, avoid trying to get to this connector....just find the wire that leads to the switch and splice into it.

The Yellow connects to a Yellow/Lt. Green wire and connects to position 1 on the switch. Blue connects to (you guessed it) Blue/Lt. Green and goes to position 4. The Brown goes to Brown/Lt, Green, and connects to position 6 on the switch. (Position 2 on the switch is Ground ...BLACK wire).

Hope this helps. I would avoid cracking open the motor as there are bushings and bearings and brushes to deal with, but if you feel competent, then knock yourself out. I know that Joe Curto can rebuild these little Lucas motors, but last I heard, he was quite backed up with work. Someone else on this forum can probably recommend an outfit.
