Should anyone need to rebuild part of their harness at the Lucas 2PR power resistor, that part appears to be AMP connector 43-14803390 (10 pin from the PDF)
(EDIT: more likely TE PN 1-480286-0 …see further posts after this one).
Very timely posted information. I have a resistor pack on my bench opened up. The plastic connectors are partially broken. There is however a difference with mine. It has 2 connectors, each being a 5 pin connector, with only four used on each connector. They stack on top of each other. One connector used for each side of the circuit board. I should be able to post a pic a bit later. Did you buy the item you posted and does it mate up with its existing other half ? Or, do you think it would require buying a connector for the injection harness and a matching part to replace the connector inside the resistor pack ? SD Faircloth
Replying to my prior post. I believe my plastic connector use to be a one piece connector. The plastic bits seem to be broken that would have held my two pieces together. I saw several listed on E-Bay a bit ago, and they were one piece. An interesting note however, the pins are held in place by separating a section of the pin, once pushed thru the connector holes. The pins are slotted and apparently once pushed thru, the pin is spread apart, causing the pin to “catch/lock -in” on the connector. SD
I have one opened up too, which spurred me to have a look for the connector (yes it is a single one piece part, not split). I used th 95/96 V12 Elec guide that ID’s the connector as a 10Pin Amp part. I got lucky and found a picture of the 8Pin version, which via that company’s catalog let me ID the “Old” 10 pin part numbe." That PN was similar enough to the new TE PN that I was able to find the drawings that matched (or look like they match) both the M and F sides of the 10Pin (2 rows of 5 with 4 pins used) connectors. On the V8 versions of these 2PR packs, all 5 wires are used on each side.
I haven’t bought the connectors SO I can’t materially verify they work, but they darn sure seem to be the right part.
Yes on the one I have it’s a single piece. There are a couple of ways the connector could be assembled in the Alu body, but I’m guessing short wires w/ the ends are assembled into the connector, that’s slid into the body, and then the ends are soldered onto both circuit boards (the wires seem a bit stiff to do the reverse, but I suppose that’s possible as well.
The M and F parts have different PNs, so i assume one could buy just one or the other + new crimp pins for whatever refurb is needed.
Had another look at the pins. The pins crimp onto the wiring. I’m gonna say they are made from spring steel and have slits running lengthwise along what I’ll call the shaft of the pin. The pin itself when pushed thru the plastic connector collapses onto itself, reducing the OD of the pin, such that it will fit thru the hole in the plastic connector. Once the pin is fully thru the connector hole, it spings out and locks it in place. A similar spring type fastening action is used on the connectors used for the injector connectors. I just tried, and it is easy to use a small curved pair of needle nose pliers to collapse the pin and push it out the hole. No need to buy a new pin or wiring. The alternate, if you were unable to remove a pin(s) from the plastic body, would be just break the plastic body and free the pins. Best to verify the new connectors will fit the case first !! They appear to be cheap enough. SD
Addendum. The “actual” part on the 2PR side is probaby: 1-480286-0
1-480389-1 is also panel mount, and might be the original PN (being a far older desig, but it looks to be the same, except in the color black. ENG_CD_480389_F.pdf (66.4 KB)
The reason being that’s considered a pannel mount connector - not a free hanging (in-line) connector.
