hey guys, im new to these forums, im not sure if this is the right section.

i just needed help with afew problems i'm having.

i've read up on how to do it yourself. got most of the info of this site. and i've previously installed headunits for a number of cars (for friends) yet this one has got me thinking.

ok long story short headunit is in. playing fine. (also did sub and amp) re-wired everything. nicely. only thing is...that wen you go to turn on your headlights...(the center lights with all the temps. a\c things and also the gear box lights) dont seem to turn on. i ran my fingers double checking over everything. fuse's. the only thing i can think of now is if i have the wrong ground connected. would that affect those lights?

any help would be great. i've also researched the wiring diagrams as well so i will double check everything.

btw. its a 08 yaris also 4door hatch.

Check your HU's dimmer connection. It sounds like you are pulling down the dimmer output.
