Re: 89 200 tqa - fuse box connectors + wire help
Hi Huw. What a nightmare. The fuse box can barely come out 1 inch due to
the spaghetti below it, so its almost impossible to take out the female
connectors from the bottom. Also, I am having a hell of a time finding
female spade connectors greater than 10 AWG! This means that the one
wire that goes to the power mirrors, that's also tacked on to the power
wire at the bottom would not have a place to go, if I took the wires all
the way to the fuse box.
Here what I did: a) cut the existing 8 AWG wires below the steering
wheel. One had corrosion even at this point, the other was clean.
Spliced 2 10 AWG wires to these.
b) Got a run of 6 AWG wire. Got most of it into a 10 AWG female
connector. Crimped, and connected to the 1 remaining open contact on the
c) ran all 3 wires to the battery (still to be done - I'm working in the
car in the driveway with a torch - came in to take a break.)
Hopefully the combination of 1 6 AWG, 1 10 AWG, and 1 10 AWG with some
corroded 8 AWG will be enough to take care of the car's electrical
Now to replace the wire to the starter with 1 AWG! It'll be this
