Okay, so i wired up my pioneer headunit wiring harness using a diagram from http://www.installdr.com. ive installed headunits before, so its not new to me. problem is, im not getting any power it seems. my headunit just wont turn on.. i checked the wires coming from the car with a multimeter, they showed they were getting power a few times, and a few times they didnt. checked all the fuses, they all seem to be good. Installed the old headunit.. now that dosent even work? anyone have any ideas?

 

come on someone gotta know something about this dumb question, i did a search and got nothing i was looking for.

 

try just running a wire from battery,the postive one just to see if there is someting wrong with that power wire, if thats it check all the crimps, sodering or whatever you did to hook it up

 

All the crimps and what not are secure.. its strange, i dont think im getting power to the yellow wire in the car? any suggestions? are there 2 boxes with fuses, if so, where is the other box located in tthe engine bay? if so, what fuse could possibly control this?
