thanks man.
Yes on the SI. there is an amp besides the factory radio. its in the center console. by the floor in front of the shifter. The SRS controller box is there also. I believe the amp sits on top. of it. basically stay away from any wires in your car that are wrapped with yellow tape. Yellow means Airbag. I guess that i could of used line level in to the factory amp, but i wasnt sure if i could use the amp or not so i went with the 5 channel amp. To get the wiring diagram youll have to go to honda service dept and have them pull the schematic up for you. ill see if i still have the diagram but im not sure where i put them when i was done. and the diagram wasnt under the radio schematics. there was a seperate section for amplifier/sound i beleive. it took like an hour for them to find what i was looking for.
as for the wiring thru the firewall.
If you look where the wire goes under the 2 airconditioning lines. there are two rubber gromlets in the firewall there. its a tight fit to get your hand in there or anything else for that matter. in your dash in the car theres a huge air filter for the ventalation system on the passenger side. the gromlets are behind there. which is also a tight fit. I had to go from the inside of the car and then fit my hand in the engine compartment to be able to find the wire. I wasnt able to do it any other way. and i literally fought with the damn thing for a couple hours. there is no real easy way since the engine practically sits half under the dash.
The steering wheel controls are in the works. I had a few things come up that needed cash so i postponed finishing a few of the little things. the only 2 things I didnt finish was the steering wheel control, and the obdII conector.
I have to still remount the gps reciever, I found it doesnt grab a signal in the dash, it has to see the sky, and I have a u132 pcmcia to usb adapter that i still need to mount for my verizon card.
but really other then that Most of my bugs are worked out all ready. now all ive been doing lately is tweaking the software to get better load times, and making sure i get everything working 100%.
Then again, once you start this project your never trully 100% done. If youd like to know anythng else let me know.
