Re: Splicing into an Engine Wiring Harness
Ah. It might be regional/business differences. In my neck of the woods
most (but not all) the cars I see in boneyards still have their engines
in place, and that's where they stay when they go to the chipper. Tires
and gas tanks come off, everything else metallic ends up on a boat to China.

Re: Splicing into an Engine Wiring Harness
Yes, the screaming Greenies are spending our tax dollars at the
rate of a thousand dollars an engine to break their blocks in the name
of pollution, here in Kalifornia.

Re: Splicing into an Engine Wiring Harness
Stuff like this can be easily, quickly, and permanently fixed with crimps.
They make a type that has an heat-shrink insulator, so squeeze some
dielectric grease in, crimp the wires, heat shrink the insulator, and you
are done. The dielectric will prevent any moisture from getting in and
corroding. Tie the whole mess away from the exhaust with some Adel clamps to
prevent having to do it again.
It's only a car, why waste time overdoing it?

Re: Splicing into an Engine Wiring Harness
Been an electronics technician for 20 years....
Don't use crimp connectors or reinsulate with electrical tape. Both are bad
practices.
Do it right, and solder in new wires. I'd recommend you go to the boneyard
as someone else said and find that part of the wire loom, cut out the part
you need keeping everything intact from the bad area to the terminus of each
wire as practically as possible and replace the whole shooting match.
Stagger the solder connections, use rosin core not acid core solder, and be
sure to use flux on the wires.
First and foremost if you don't have experience at soldering, PRACTICE on
some other wires to get the technique down before going in. Soldering is
very easy with a bit of practice and guidance.
Lastly use heatshrink on each connection and make sure it forms a tight
seal.
