It is me again !! I have 99 Montero and always asking stupid questions !!! I have a stereo interfreence when acceleration. So, I plan to connect the power wire direct to the battery to prevent such problem. I also want to install a TFT montior too. But, I can not find any hole on the firewall between driving room and engine room. Do I miss somewhere ? Or, I should drill a hole by myself ? Thanks all you helps as usual.
