Progress continues on the 69 Camaro. We’re working on wiring the car and adapting the GMPP harness to manage our LS3. Using FabBosses to mount the ECM was easy. We bolted a 1/4 – 20 versions to the ECM, trimmed them slightly to deal with the curvature of the panel, and welded them in place. It wasn’t necessary to fully weld the FabBosses — we just put two solid 1/2″ welds on each side of the ‘Boss. Total time: 1 hour.
