Help Harness Wiring Problem

Hello everyone. so I finally got a chance to check the harness on my 1992 325is to find that I have 4 wires completely corroded and broken into two pieces and 2 more corroding but still holding together. Now I have purchased some butt connectors and self stripping tap connectors but im not sure what is the rating i should be using. I went to the store and bough all 3 different kinds. Blue: 16-14 AWG, YELLOW: 12-10 AWG, RED: 22-18 AWG

The following cables are the ones that are corroded:

Thick white: this one has burnt ends
gray and black with yellow dots
white and green with yellow dots
red and green
greay and black
brown

ANy advice on which rating to use to fix all cables?
Thanks.

You will need to just size them up to each of the wires, the red 22-18 guage being the smallest, then the blue 16-14 gauge & then the yellow being largest @ 12-10 gauge..... splice about 1/4" of the insulation off the tip of the wire, they will need to fit snug over the wire end & be sure to use the proper color code on your butt crimper to crimp the connector.

johnny,

Nice. Just finish doing the work. My locks, liscence plate light and the anoying sound when you leave the key on are working. Not sure what other functions are back online. I was hoping it would fix the computer since I am not able to read it with the B100 tool. Maybe is a blown fuse due to the wire shortage. GOnna have to check that tomorrow.

The only thing that worries me is that the wires are now exposed to water. I tried to wrap as much as possible in electrical tape but still is not 100% weather proof. Gonna have to follow up next weekend and fully wrap everything individually.

Thank you very much for your help.
