I bought the Dl8 To DL3 mirror wiring kit. The instructions were spot on and the install was easier than I anticipated. Great customer service. Phil is the greatest. Would highly recommend Harness Doc.
Thanks

I bought the dl8 to dl3 diy kit and let me tell you how fantastic it was.The instructions were straight forward and easy to understand.What’s more time consuming is removing the wire harness than installing the new wires you need.I high recommend this because every function of the mirror works.You also keep the factory look when installing the kit which is important.

Just got done installing the DL8 - DL3 DIY Mirror Upgrade Kit. This kit is awesome from start to finish with Very detailed instructions. Saved me a bunch of money on a new harness. Now I have more money to spend on some more Harness Dr items. Thanks again

Kit an the directions were excellent. Did some YouTube research on door panel removal as well as Gamboa's mirror cap removal video as part of the advance preparation for the project. Took my time and double checked everything before inserting anything or cutting anything. Didn't even break any tabs on the mirror cap. Overall took about 4-5 hours but everything worked like it should.
I did have an issue with the black (ground) wire splice and ended up cutting and soldering to make the connection. Also recommend for the parts where you need to feed the wires through the rubber gaskets - get a metal straw and feed that through before feeding the wires through that. Made it much easier.
