the stainless hose that people put the wires in look nice but retain alot of heat and if you have it to close to something hot all the wires in it will melt together and that would be BAD. Better off using the heat resistant hoses thats silverish.
also if you move the fuse box to your glove box you will have to extend alot of wires and with that a few shielded wires that if you do not re-shield will not function properly. It wouldent be that hard but no matter what we can not fully tuck all our wires due to the position of our injectors which are on the outsides. Those wires would always be visable along with our wires for our sparkplugs. which cant be hidden fully due to position as well.
has anyone ever taken the left fender off the car and seen how much wiring is behind it? Theres a lot! And to extend all of it wouldent be impossible but to do it right with out messing one solder up is a real risk IMO. Also you would then need to snake all of those wires thru under the dash to the glovebox and then cut into your firewall and figure out how long to extend all those wires that go into the engine bay.
it would take much longer then one weekend. It would look sick if you could get most of it hidden and cleaned up but its alot fo work. Civics are easy they have half the wires we do. Im not saying it cant be done im saying it would be harder then everyone is expecting.
But hey if someone finds a way then thats awsome . id totally rock a wireless engine bay without a doubt.
