Wiring. Sigh.There has been a terrible mistake.
Well. Probably
more than one.
We already discussed the damage to the forward harness. I
went to a junkyard and found a car (a Pontiac 6 cylinder, at that) and got a new
C200; had to re-pin a few things to line up with the V8 bits.
|
Not pictured: I scanned in about 170 pages of connector drawings and
schematics from the Helms manual. I actually found some errata, not
that I know who I'd tell; the books are almost 20 years old.
I also
made a master spreadsheet with the circuit numbers, and what each end of
each wire is.
I saved off a set of the completed scans, I'll make my
notes and change the things that need changed (remove ABS, EGR, etc.; change
the plugs for AC fan, headlamp, etc.), then print and put in a binder for
future reference.
In this picture I started labeling the wires in the
damaged harness as I could probe them and figure out which is which. I
probably should have just found an undamaged V8 Chevy forward harness -
there's at least one more junkyard run coming. |
Started connecting the new C200 to the cut portion. | |
|
Lots of labeling. The labelmaker ran out of tape, so I moved to
handwritten. |
The process of combining both ends is very time consuming. | |
|
At least I could use this for both the soldering and the heatshrink. |
It is progress, of a sort. There are issues that I don't quite
understand yet.
For some reason, this connector is not just to hook
the front harness to the mid harness. The ignition switch and the
instrument panel fuse block are on opposite sides of this block. I
think there's more missing connectors but I can't tell; surely the General
didn't expect solder and heatshrink to replace a front harness. It
looks like most, if not all, of the remaining wires coming through the
firewall here will go to things other than the C200 block. | |
So really this update was just so I don't get out of the habit of updating; the
work progresses, slowly. The wife suggests that I do garage while it's
cool out, and worry about this when it's hot out. She's probably right.
I've got the pinion depth gauge, the bearing race driver, and the bearing
splitter I need to do the rear axle... it just scares me.
Also need to finish the needle scaling of the underbed, to powerwash the fuel
tank and remount, to finish welding the bed front panel flange, to figure out
why my MIG is not welding well. Much to do. Plenty of time, but much
to do.
Go back to the previous day (7 Apr 19)
