87 GTA Wiring Harnesses
Does anyone know where I can get complete engineering drawings of the wire harnesses for an 87 GTA 5.7 TPI? I am rebuilding a car that had a dash fire and destroyed the harnesses under the dash, the c100 connector and burned through and took out most of the wiring along the outside firewall. I have bought a couple of harnesses from ebay but most seem to be damaged or the wrapping has come off. I would like to get the engineering drawings so I can repair the harnesses back to factory original. I have the Pontiac service manual and the drawings in there are no help at all. If anyone know where to get these, please let me know. You can PM me or email me at blake_foster47@yahoo.com or blake.foster@nilfisk-advance.com

Re: 87 GTA Wiring Harnesses
The circuit diagrams in the FSM are the best you will get but as you are aware they only show connections , not dimensions
Why can't you use them as templates for measurements for building a new harness ?
