I am working on a rebuild of a Gem EL I purchased as a project. I have a wiring diagram and have sorted out most of the wiring the previous owner attempted. I have a group of wires (4 wires) that are grouped with the rear light wiring harness above the batteries. Two blue wires , yellow tracer and purple tracer I believe, black and a red wire. What do these go to ? What component is housed above the batteries. Thanks for any help ---

Are they all mounted in a plug? Or just terminated individually with spade connectors? There is usually a bundle back there for added options. I’m trying to source out the matching colors with what you see but they change depending on the doc I am looking at. The Blu/Yel should be the back up light. The Red should be the Center Brake light. Blu/Pur - _might_ be the Lic Plate light ← not sure Bk - might grounds for these Confirm with a meter and flipping some switches. That being said, the other things that will have connectors around the top of the battery pack will be the E-brake switch and the batt temp sensor. The colors you are quoting are not related to these two items. ---

Thanks. Yeah I don’t see where anything was mounted in that area. Will check with meter and see what energies them once I progress in the rebuild. ---

Temperature sensor may be routed in that bundle. Look for same color connected to charger white under dash. ---

Yeah. Found temperature sensor wires but goes into main distribution block. Someone else suggested that extra wires were for options. ---

Gem Rear Harness. Connector 1 goes to J6 on PSDM. Is this what you are seeing? Special attention to 9, 10, 11, 12. ![Gem rear harness1](https://canada1.discourse-cdn.com/flex030/uploads/electricforum/original/2X/3/382fed13a950cf3e81cf0a94c06ce3af11957c9c.jpeg) ![PSDM Rear harness2](https://canada1.discourse-cdn.com/flex030/uploads/electricforum/original/2X/7/71a345f68297b7c4afbfeeaccfebb1834b49720c.jpeg) ---
