The 2 best reasons to replace your 30 odd year old efi harness.
2 litres per 100km.
They are the reasons.
I remade mine using 4mm wire and some patience. Not the original colors, but its not easy, or cheap, to get all the right colors. But by going slow and doing diagrams along the way, I've made a new harness, installed, for under $25 Australian.
And yes, better fuel economy, slightly more power and a happy me.

Most people think stuff like this is hard. It is not. It's difficult, yes, but as long as you take your time and ensure you're following the correct diagram and/or instructions, most things are doable.
BTW, I replied to one of your classified ads the other day, or did I forget to press send? About the bumper.
Cheers

Nice work. Replacing key areas of crusty old wiring goes a long way to keeping our old beasts alive.
Electrics seem to be a binary thing with most people, either you are comfortable with it or shy away completely. I guess its the potential (pun not intended, but I'll take it) for doing further damage.

Well, I've taken the prowler out and about and it definitely runs noticeably better. Fuel saving may be even better than above. Normally, if I'd filled the right tank, which I did, before I head down to a mates restaurant about 130km from here, the needle would go below the empty mark. It doesn't go all the way up BTW, and once it is on empty, there's probably 15-16 odd litres. Yesterday, didn't quite fill up, maybe 5 more litres would have fit, went down, faster than usual, came back again faster than usual, needle is just above empty!
And, despite being covered in frost this morning, turned the key and bang! Started instantly!
Hopefully someone out there sees this post and realises that you sometimes can make your own parts. I'm sure some people would never have thought to try or that you can.
The main tip is accurate drawings are essential. Wiring for the new plugs

Yes, you can get them and the rubber boots online. I've ordered them but as I'm doing a lot more work soon, I just used these, taped one, marking the other end so you know which wire is which, and then taped them together.
I'll be making yet another harness when I do the head and I'll put the plugs on then.
These were 15 per pack for $3.95 per pack.

I've got some wiring to do myself on a slightly older beast with V12 baked and hardened insulation. Did you get your wiring on line or at a local supplie? Is that a heat resistant woven sleeve it's in? eBay? Is it ok to plug suppliers on this forum? Thanks in advance. Alan.

Hi,
I used standard 4mm wire sold on a 7m roll for $7 per roll available at any auto store or most hardware stores. The plugs I've used here came from a shop called jaycar. The plugs for after the rebuild with the proper connectors were ordered online by a friendly local efi mechanic.
Braid and tape both heat resistant, and in auto and hardware stores.
