I have a 85 k10 and was wondering how to hook up the stock temp gauge. I have the stock temp gauge already in the dash but I have now wiring. I was wondering what all I needed to have to hook it up so the the original gauge works.
-
The wiring from the factory is in the harness and comes out of the fuse box bulk head. Are you saying someone removed it?
-
Yes everything has been removed from the original gauge. I currently have an aftermarket one in there
-
You will need to put the wiring back to the cluster to make it start working again.. If someone removed it that were determined if they got it all out.
-
Do u know which wires they are by any chance. Plus what would I use for the wire that goes from the engine block to the temp gauge

Use the 1985 Wiring Manual (http://www.73-87chevytrucks.com/techinfo/7387CKMans//Wiring/ST_352_85_1985_Chevrolet_GMC_Light_Truc_Wiring_Manual_CK_10_30_Only.pdf) to help identify the correct wire cavities passing through the bulkhead and instrument cluster connectors. The factory temperature sender wiring is dark green. Wire spec is 18-gauge, crosslink GXL or SXL available from Terminal Supply Co (http://terminalsupplyco.com/Store/Product.aspx?pc=18+GXL-100-GRN), Del City (http://www.delcity.net/store/Cross!Link-Wire/p_804928) and many others. GXL/SXL is slightly more costly than "parts house" wire, but better tolerates the high heat and ozone in automotive environments. Circuit routing between the cluster connector and gauge is via a flexible printed circuit board that is application specific.
