Rep Power: 373

Alright i bought a pioneer 6800 and installed it myself the other day just really quick with electrical tape, now i went about some connectors to hook it up and now i have nothing at all, there is no power to the headunit and the keyless entry doesnt work either, i checked fuses but they seem to be fine. I have even rewired with electrical tape and double checked the connections between the headunit and harness... Everything worked fine yesterday now all of the sudden its like dead basically lol... Any help before taking it back to bestbuy and having them install it? i have ran out of ideas... thanks...

fuse!! also not sure how true this is since i still have stock head unit but dont you have to leave the stock unit hooked up in some way to use stock keyless entry unless you have an aftermarket alarm??

do you have any idea which fuse? i have checked the fuses you can pull out underneath the steering wheel and the ones under the hood, i didnt see any that would cause this problem...

Thats what i thought also but couldnt find any. so any ideas as to which fuse and where? thanks for your help guys!

so this should fix the remote entry and power up the headunit now?(well after i disconnect the battery and re-connect the wiring to the headunit.)

okay the backup fuse fixed the keyless entry.... now what about the black headunit still, its not getting power at all it seems like.

check on your radio harness if your getting constant and ignition power. if your getting both, check your ground wire, if all 3 are good, then you might need to push reset or something, or maybe a fuse in your headunit or in the back of the headunit. if you dont got power in 1 of your 2 power wires, check all fuses again.

checked the fuse on the headunit and it was okay. i am not sure how i would check for a constant and ignition power.

the yellow and red wires going to your headunit are your 2 power wires, the yellow should always have power no matter the key position, and the red one only has power when the key is in acc or run. to check if you have power on those wires use a multimeter or test light. put one end of multimeter on ground and other end on yellow wire, then do the same on the red wire and ground and turn the key to acc. multimeter needs to be on volts dc.
