Mustang PCM Harness Firewall Grommet
This grommet is used to seal the PCM computer harness to the firewall on most 1983-2004 Mustangs. This 5.0 Resto rubber plug will replace a missing or damaged grommet where the wiring harness passes through the bulkhead on the passenger side of the engine compartment. Don't let this little grommet be the cause of serious PCM damage on your Mustang, grab yours today!
Quality neoprene firewall grommet seal for just about any EFI conversion project. Late Model Restoration has everything great going for it, including great products like this and fast shipping, but they did neglect to provide the customer with the dimensions of this seal on their website. So now that I have this part in hand, the dimensions are as follows: Firewall Hole: 3.00" L x 1.55" H (Oval hole) Harness Hole: 0.80" ID Overall Thickness: 1.50" Channel Groove for Firewall: 0.20" (Max thickness of metal for firewall at hole)
I used this grommet for a retrofit engine transplant of a 2006 GM LSx engine and PCM into an custom vehicle application. The (2x) long 80-pin PCM connectors were able to fit through the oval hole dimension for the grommet at the same time, followed by snapping the grommet in place. No other grommets on the market today would accommodate passing these large PCM connectors through the firewall. Thanks to the uniqueness of this grommet, my project is a complete success!! Well done Late Model Restoration!
