Nigel Posted June 21, 2001 Share Posted June 21, 2001 So, my plan was to mount the SDS ECU on the driver's side kick pannel (to the left of the clutch peddle). I have a 240, so that would involve drilling a rather large hole (1 1/2" max) through the firewall in order to fit the wiring harness connectors through. The question is, how do I seal up the hole? I've looked through a couple of electronics catalogues, but I don't see any grommets big enough, and none that will actually seal around the wires like the grommet for the factory wiring harness. I might be able to get a 280Z FI harness grommet, but in case I can't, I'd like some suggestions... Thanks all! Nigel Quote Link to comment Share on other sites More sharing options...
Drax240z Posted June 21, 2001 Share Posted June 21, 2001 Nigel, I mounted my SDS ECU in the exact same spot, but on the passanger side. The main wiring harness passes through right there, and you can fit all the SDS connectors through that hole without any cutting. This is on a 72.

Guest Anonymous Posted June 22, 2001 Share Posted June 22, 2001 I used a 1" grommet, but I cut the hole 1 1/2" x 3/4". The connectors went thru the grommet first, then I shoved the grommet into the hole. Quote Link to comment Share on other sites More sharing options...
