Firewall Hole on Prostar

[Nilao]

I have one of those. I hope you're good at soldering as both my head display units burned out. The second one I kept and dismantled. Their capacitors are low quality and had ruptured from heat. I replaced all three that power the cameras and put 2 20 mm fans on the back to blow air into it to help cool them. Also be warned that qualcomms do not like them. It blocks the GPS signal AND causes error messages.

I had placed 1 on each mirror facing rearwards and 2 on each A pillar by the windshield facing forwards. I see all around the cab with the exception of about 6 feet on each side.
