Rear Harness Tips 74 RR...

[ramairthree]

Ok, the good news is I have turn signal, headlight switch on power to rear and side markers, and brake pedal power all going to my tail light harness connecter in the trunk working as it should.

The bad news is,
between the shaved side marker lights, and several other hacks,
I am having trouble making heads or tails of the harness that connects to that.

I am used to just popping the trunk and accessing everything. My access to the harness with housings external to the trunk is hampering my progress.

For experience third gen B body owners,
what works best for you.

Pull entire harness and sort out

remove rear valence and work on from under car with bumper on

remove valence, bumper, sort out then back on

basically,
what ends up being the most efficient and accurate way to sort it out?

While I have the manual and great wiring diagram,
I have no intact car to compare it to.

well, now I have some power to my passenger rear lights (and a wasp sting).

I wondered why I had looked in the manual several times without seeing tail light bezel into, etc.

Then it occured to me that at some point, I had another 74 b body manual. duh.

everything I needed to see in there.

well, I spent an hour and a half trying to sort out my rear lighting.

I get the normal power I should going to the rear harness connector.
from there it is madness.

the driver's side housing is not hooked up to anything,
the passenger tail light housing is,
and after 90 minutes I have succeded in getting the outward passenger side bulb to come on with braking and turn signal, but not headlights, and nothing on the inward bulb.

I have lots of wire I don't need and missing some I do.
