Thermostat Power Wiring Harness Stripped! What to do? Please help!

Hey fellow e90posters....I needed some help if anyone would be able to chime in...

I just finished changing my water pump and thermostat on my car...Everything went well with the exception of one thing...When I was buttoning everything back together I noticed the power cable/connection to the thermostat (2-wire plug) was stripped and exposed....One of the wires was barely holding on and seems to be a hazard...The metal wiring was exposed and pretty much is about cut....

Is there a way I could buy a new end connector for the thermostat and somehow splice it in? Please let me know as I am not looking forward to tracing the wires all the way back if thats what I have to do....that will mean uninstalling water pump/thermostat and working backwards...

Someone help! Not even sure if there is a part number for just the thermostat harness that I could cut and splice...Thanks in advance to anyone who responds!

If you cannot find the connector, I would cut the connector altogether on both ends and splice them up. Use black tape and secure them tight.

You should be able to get a pick or terminal tool in the connector to release the wrie ends and then reuse the terminals on new longer wires. Then splice those into the wires already connected to the main harness where you snip them. Voila!

Did you order the replacement parts then put that together? I just had the same thing happen to me. Just looking for a bit more information. Thanks.

yes , its individual parts thats being put together , you will need the crimping tool to get it nicely done, with the tool its a fairly easy job.

you could just solder the terminals instead of buying the tool, and replace your motor mounts, they are worn.

I have these parts in hand. Was wondering if you could help me with a few details. Is this 24g wire? Also in what matter do the pins need to be inserted? Or would you recommend pulling the old one apart as reference? Thanks for your help.
