I have a 06 trailblazer LS rear wheel drive I first switched only power side mirrors to the ones that have T-singnals and defrost with plug and play everything else was already there. (Went to junk yard no TB with side mirror turn signal so I took them off a envoy perfect fit)
Then I switched cluster to DIC,only thing I have noticed is maybe since it came off a 4-wheel version my traction control button is not coming on dash, not sure if it's not working or just not being illuminated and oil guage did not work until i cleared codes in obd2 ?immediately oil guage came on. Gives all other notifications so far...doors,check guages,low gas...ect
