SD UVCH

I definitely wouldn't use butt connectors.
I hate those things with a passion.

Solder only.

not the same wiring order, similar idea though
the outer 4 are glowplugs
does IDM ground the injectors or send power?
whatever it is, the center is the Common and the 4 remaining are the individual injectors
so the conversion has an extra wire that if you chase it doen the harness is spliced between the bank plugs, I just cut it out.

I will say I definitely had an issue in the valve cover harness, and I think it killed this motor.
I think 5&7 were cross talking

Hot power is the common.
The four individual are ground signals from the idm.

Kay gotcha guys on the Butt connectors.....when I do this I'll do solder and quality shrink tube. Any actual schematics or pix of this or a write up?

Thanks

There is nothing wrong using a butt connector. You have to know how to make the crimp properly. I would not use an isulated generic connector. I have used plenty of non-insuated butt connectors sleeved with shrink tubing. After you crimp, to have to do the pull test.

Be careful when soldering; if not soldered properly, the wires can get brittle and crack.

Right on point Billy, this is exactly what I do. I rarely use the insulated ones, typically I will apply dielectric grease to wire, slip in non insulated butt connector crimp then shrink quality tube over the connection.

My experiences with solder is not as good as I find the need to have a spotless connection area grease free, which might be a bit of a challenge under the hood, guess I could pull out the entire harness though.

a little flux makes soldering a lot easier.
I did non insulated, soldered, and shrink tube'd

Why not use a butt connector that combines crimping, soldering with view window, and adhesive heat shrink all in one?
Such as NSAP versions?

I used those on non-critical applications. By the time you get the solder hot enough, you burn the heat shrink and some of the solder leaks out.

On another note, I'm looking into making an adapter harness that plugs into the stock plug then into a SD VC plug (play and play). I have re-pinned the stock harness when it burnt, I have the pins that go into the plug. The pins are a Delphi's. I started to reverse search the connector but got side tracked....too many projects going on.

So SD VC gasket - SD plug - custom wire harness- OBS plugs - custom plug - OBS stock wire harness? Got any pix Billy? Just not seeing what yer saying sorry.

OBS harness plugs-adapter-sd uvch
I believe is what he means.

I mean may be useful for some, but most that are doing the SD UVCH need new pigtails anyways.
Definitely look cleaner.

I took it to mean remove the connector shell on factory OBS wiring and utilize a 8 or 9 way weather pack, with the opposite side on the SD vc harness. Seems like it would be a good idea.

79jasper · Mar 15, 2014

Not sure.
We'll wait and see when he gets back at us.

I found my notes on making an adapter harness to plug into the stock harness then into SD VC. Yes, I thought about removing connector bodies and installing the SD connector body. My concern is the front plugs/wires reaching the center of the valve cover without splicing/cutting. I want to make the adapter harness to be plug and play.

The replacement terminal for the harness is International 1667742C1 (female) which looks like a Metri-Pack 150 terminal. I have to confirm that the harness terminals are in fact Metri-Pack 150. I know I have some of the International terminals lying around. I have to see if I have any Metri-Pack 150 terminals around.

The problem I see with the stock harness, is the outer terminals are always burning up. The outer terminal are for the GPs. There has to be a reason why they are burning up. Correct me if I am wrong, the SD harness has a heavier gauge wire for the GPs vs the OBS harness. Why is the SD VC superior to the OBS one?

This project went on the back burner at the time as I am getting my race car ready for the upcoming season. Plus, I am working on getting my truck live tuned.

they do have bigger pins for GPs

Well turns out my harnesses are fine, and my glowplugs were bad.
Literally all but one were dead. And the one that read was 1.5 ohms.
I noticed my Injector clips weren't all the same. 6 of 8 had the plastic clips. These two had the metal clip thing.

Patrick Feeley · Nov 1, 2015

The plastic clips are the early style of UVCH. They also had little seals on the injector connections. The newer ones use the "bail wire" clips with no seals which aren't needed (and won't fit anyway). Cheers!
