Does anyone here know where I can find a new engine wiring harness for a small block 350ci with an HEI Distributor? I have a painless wirnig system, but I only have the wiring from the firewall back.

Need help.

If you have Painless... you are pretty much stuck with either Painless or building it yourself.

Do you have any kind of firewall bulkhead connector?

Yea, but its in pretty bad shape :(

By that you mean the bulkhead connector? And taking that a step further, the original factory bulkhead connector? Both halves?

My experience is that the plastic in those connectors will last forever. The terminals are another story. But fortunately the terminals are all *very* replaceable and available. On the engine side the wires were sealed in with some kind of sealant that can be pried and scraped out along with any accumulated dirt and gunk of ages.

The terminals are what is called "type 56" and come in male and female sides. The male is a basic spade that can be squeezed with needle nose pliers to unlock from the holder (bulkhead in this case). Once unlocked it pulls out the back of the holder.

The female is just slightly more challenging to get out. If you look at the end of the holder you will see a small notch. If you insert an appropriate sized tool into that slot you can push down the locking tab. Then the terminal pulls out the back side of the holder. I was doing enough of these that I made up a special tool for this using a chunk of sheet aluminum cut and filed down to fit the slot optimally.

Of course there is still the question about how your Painless system is setup. I thought the Painless setups were complete harnesses and not just dash-only or partial harnesses. I would guess that you have a Painless fuse panel and that it is not hooked up on the other side of the bulkhead? And you probably have some wire bundles from Painless that are supposed to go out front into the engine compartment? And they probably did not say how you should go through the firewall?

You probably want to provide some more specific details so you can get more specific answers.
