    Couple of nights ago my engine stop on me. I started up a minute later it turn off on me. This happened 3 times the 4th time it started up and I was able to drive home without it shutting off. The next day i drove around the block to see what will happen, and it did shut off again. I hooked it up to the techstream it read P261B. So I order a new waterpump. when I was removing the old one I decided to test it out before I unplugged. The water pump turn on fine which made me wonder if I was changing the wrong thing.... my thought is since I was able to drive home maybe it only work sometimes... what yall input

    Do you have a junk yard nearby? I'd call around if Toyota can't get you just the connector with wires and terminals attached. Also check eBay, car-part.com, and craigslist.

    When soldering into your harness use heatshrink tubing so that the copper doesn't corrode.

    Godaca LLC has all kinds of connectors. I just ordered my NSS connector from them with pins and WP inserts
