Our PJ058 and PJ059 harness connections for HP / Compaq

The images below show contact assignments for our jacks PJ058 and PJ059, both old and new styles, (Left) and the most common jack (Right) found if not like ours. You can compare the assignments and simply connect what ever color wire to the corresponding contact on our jacks. You will notice that our old style PJ058 and PJ059 only has 1 contact for power and 1 contact for ground. If the jack you have has more than 1 power or ground wire just connect all of them to the corresponding contact on the new jack. Our new style PJ058 and PJ059 has 2 power contacts and 1 ground contact. Simply connect the wires to the corresponding contacts as you would the old style. However, if the jack your replacing has only 1 power contact you should run a small jumper wire between both power contacts of our new style so that you are not using only 1 side to power your system.

There are some basics you need to know. There are 4 basic contact types for any of the HP / Compaq harnesses that use the PJ058 and PJ059 style DC Power Jacks, DATA, POWER, LED POWER and GROUND. Your DC Power Jack may have 5, 6 or even 7 wires on it but they will ALL fall into one of the 4 contact types. If you look at the images above you can see the layout for the contacts of our DC Power Jacks PJ058 and PJ059, both old and new styles. There are several jacks used by HP / Compaq for these harnesses. For those that have 6 or 7 wires you will have multiple wires for the power and/or ground.

Pin 1 is DATA. It is used to allow communications between the system board and the AC adapter to control power output. It connects to the small pin inside the barrel of the AC adapter plug tip and is generally located closest to the center on the back of the jack. Wire colors can be pretty much anything other than black and red. We have seen, Green, Orange and White.

Pin 2 is GROUND. This supplies Ground to the DC Power Jack and connects to the outer surface contact of the AC adapter barrel plug tip. Wire color Black, if your jack has 5 or more wires then you may have multiple ground wires that can all be connected to pin 2 of our PJ058 or PJ059. Some factory harnesses have the ground contact bridged by solder to the outer casing of the jack.

Pin 3 is POWER. This supplies Power to the DC Power Jack and connects to the inner contact surface of the AC adapter barrel plug tip. Wire color Red, if your jack has 5 or more wires then you may have multiple power wires that can all be connected to pin 3 of our PJ058 or PJ059.

Pin 4 is LED GROUND. Virtually the same as pin 2, wire color Black(if not soldered to the outside case).

Pin 5 is LED POWER. This is active if the system board is receiving power from pin 3. Wire colors can be pretty much anything other than black and red. We have seen Green, Orange and White (if you have Orange for both DATA and LED POWER we have seen that the wire for the DATA pin will have a black mark on the end)

Tips: Pins 2 and 4 can have a solder bridge to the case crimp tab between them to complete the ground for the LED GROUND instead of using a wire. Simply bend pin 4, the LED GROUND contact, over and on top of the case tab and then solder the ground wire(s) to pin 2 using enough solder to also bridge the gap to the case tab. At least bridge pin 2 to the case tab with solder so the casing is grounded.

When done you can cover the back of the jack and wires with hot glue to keep the wires from touching each other and to protect them from other contacts. You can also use shrink wrap tubing on each wire but this is very time consuming.
