Need help please. installing an American Autowire classic upgrade harness. Purchased a replacement wiper motor from NPD. Motor has a plastic 4 position wire connector. Original motor had a rubber 4 position connector that matches the new harness I purchased. Decided to cut the old rubber connector and replace the new plastic connector so it would be a plug and play situation. Soldered red to red, white to white. figured there was no way that would be wrong. Then the black wire I mated to green , which left only one wire, which I believe was blue at the motor and I cant remember what it was on the American Auto wire plug. Is this correct?
