Feeding wires through conduit

I have to replace the spark plug wires on "Old Sarge" pretty soon anyway (#4 wire had a bad run-in with the front pulley). Eventually, I'm gonna get the 6V ignition system back on its feet with a new wiring harness. Question: if I change out these spark plug wires now, how big a pain is it going to be to change that wiring harness later? Either A) its no trouble at all, and I can come back to it later, or B) its a pain in the neck, and I better change 'em both out at the same time.

Thanks in advance for the input.

I just got thru running new plug wires and harness thru my conduit. It wasn't that difficult, but you will have to remove the harness from the tube to install new plug wires so you might as well do it all at once.

The first step is to clean out the conduit with one of your wifes bottle brushes. She won't miss it, and you can get her a new one as a gift.

Next, tape a piece of string onto the end of your harness and run the string thru the conduit. Pick your longest plug wire and run it into the rear most plug wire hole. useing LOTS of WD-40, run your next three plug wires thru the conduit and let them run long out the other (dist.) end. Now pull on the string and pull thru your harness. If you want to do it right, you can pull the generator wire back in and run it thru the small hole on the dist. end of the conduit.

Last, set the conduit on the engine and measure where to cut the plug wires. Take it back to the bench and cut and solder the new wire ends on for the dist. Don't forget the rubber boots before you solder! Bolt your conduit back on, re-torque your head, hook up the wires, and go play!
