Helping a friend do a lithium upgrade to his 2014. He tore out the Delta Q to have the algo changed but didnt label his wires. Charger is back in and Im completely at a loss where the Green Interlock wire goes. It has a male spade and there is nothing within reach of the wire to even attach to. Anyone have an idea? Diagram shows it going to the PSDM. ![image](https://canada1.discourse-cdn.com/flex030/uploads/electricforum/original/2X/8/8506b4bb24d2ad2ee9bafaa340f37a374f522c88.jpeg) ---

## If your running a Lithium profile = DQ Black to Controller Negative DQ Red to Battery Positieve If you have a four wire DQ then the White wire from the DQ goes to any -72 ground and Green from the charger go to nothing- tape it off. Green wire from Gem harness goes to any constant 72+V If you have the newer style DQ then pin 1 goes to 72V ground, like White wire above. ---

Thanks Mike, I saw an earlier post of yours and was going to DM you. The harness plugs into the PSDM, off that is a black with a ring, I’m guessing that is a 12v ground, right to the frame. The red I have right now going to PSDM 72+, black to PSDM 72-. I can easily put that to the controller pos and neg. I have to check the profile Dave put in, if I remember it’s the 98v. White to the temp sensor Green cap off ---

Car won’t run without the green interlock power from charger. White goes to BMS or B-. ---

I’m at a loss for this green. It just doesn’t have a home that I can find. White goes to an orange with blue stripe, that heads to the rear seat. There is a temp sensor… ![image](https://canada1.discourse-cdn.com/flex030/uploads/electricforum/original/2X/9/92445598905010039138056e3377384af6ea327a.png) then an orange with a black stripe heads back to the PSDM -72v. That does also go to the B- on the BMS. ---

It all changed with the Lithium profile on the charger - Ignore the orange and orange/black wires now. White needs to be -72v grounded, you can do that from the charger black wire or any other -72 source. The green wire in the harness of the GEM can go to any +72v source or I guess the green wire from the charger can connect to the green wire in the harness as @Inwo has said, but I have always just hooked it straight to +72v and capped off the green wire coming from the charger. ---

Awesome, thank you. The harness to the PSDM has a black with a grounding ring. That would go straight to the frame? ---

It might but you don’t want the White wire to the frame you want it to -72v from the battery, the frame is 12v. ---

This green in the harness? ![image](https://canada1.discourse-cdn.com/flex030/uploads/electricforum/original/2X/4/48c9679e294b3334515b7f18d5eeabee82e51c6c.jpeg) ---

I don’t know I have never followed mine a the way to the PSDM. Where does the other end of that green wire go? ---

If the car runs it’s fine. If not it needs +72v from charger. The one Mike runs to B+72v normally gets power from charger. Then car doesn’t run when plugged in to ac. ---

Oh. Did not know it had a dc/dc converter in it. Your pic is all correct. The connector plugs in to your PSDM under the dash. ---

Thank you gentlemen. Dave, thats what Im thinking, but I cant find it! The connector (male spade) on the green doesnt have a mark on it, so Im thinking it must not be used. ![image](https://canada1.discourse-cdn.com/flex030/uploads/electricforum/original/2X/7/77dc1c1a4c1b61d2f78321d895edbf5ea8419fc7.png)
