i had the same problem with the wiring in the doors until i found an easier way of getting the wires through the rubber gasket thingo. its kinda hard 2 explain without havign to literally demonstrate it. im not willing to pull apart my car at this moment especially coz its raining atm... but ive taken a pic of the general area and drew up what you should do.
the pic ive taken is from the passenger door. the wires that run through to this door (on my car) are:
electric windows
stock speaker wires
so what you gotta do is -
1. identify all wiring that runs from the door to inside the car
2. locate the end of the wires that is found inside the car
3. disconnect the wires from this end.
4. do the same with the other end of the wires - disconnect wires from inside the car
because all the wires are disconnected, it is much easier to pull the gasket out.
you will probebly need a flat screwdriver to persuade the gasket to detach.. much the same way you would use a spoon to take the lid off a can of milo.
the gasket is rubber.. its strong and it can bend, so you wont damage it at all.
once thats done, pull the gasket towards you so that the gasket and wiring hangs loose.
when its loose, you can easily feed the new wires through!
to run new wires through the gasket:
1: poke a LONG flat ended screwdriver through the gasket
(make sure you have the correct length of wiring and feed it through the hole that leads to the gasket)
2. sticky tape the new wire to the end of the screw driver
3. pull the screwdriver back out of the gasket- the new wires should have logically been fed through with the screwdriver.
4. pull the rest of the wire through the gasket
5. reconnect all wiring inside the car
6. push gasket back into place on the car side
7. reconnect wires in the door
8. pull the wires in... this will cause the gasket to be put back into place
wish i took pics of me doing this while i was installing my punch's... but once i figured out how 2 pull out the wires and the gasket properly, it took a matter of MINUTES to complete.. instead of hours trying 2 fiddle around with the very LIMITED space your fingers have tryign 2 guess your way through.
