    Mounting Location of Courtesy Lights

    It is my understanding that some trim levels offered factory courtesy lights. Anyone have a good photo or description of where these would mount? I have a set from Painless and have wiring all sorted out, but needing advice on where to mount them. Thanks in advance.

    Speedo Driven Gear Issue

    Speedo Driven Gear Issue

    My radius is 16.5” from ground to center of hub. So you are saying I should be using 33” instead of 34.9 for diameter?

    Loose unused 2 wire plug near steering column

    So, the vehicle only starts in park or neutral already. If this was for neutral safety switch, wouldn't that be impossible? and there is not a pair of male pins available to accept the plug on the neutral safety switch…..confused.

    How to diagnose speedometer head issue

    Yes, I just installed a 3.73 ratio a couple of weeks ago. Paired it with a 39 tooth driven gear, verified I had a blue 18 drive gear, and a new cable. Tire diameter is 34.9. TCI says everything is correct. Speedo acting wonky. What’s the best way to trim the cable end? can I use tin snips?

    I already have a multifunction lever switch with cruise control compatibility. What other items are required to convert a vehicle without cruise to make it functional? Forgive me if this has been discussed but I cannot find reliable info. Thanks.

    2 wiper motor pump symptoms….what would you do?

    No difference between Hi and Low setting on wiper speed but motor does function. No wiper fluid pumping. Since the pump is part of the motor assembly, would you just replace it and hope both issues resolve? I hear wai is better than the cardone for replacement purposes…….

    Green is an option on 700r4? I’m not showing that. I’m showing 15 teeth is grey. I’m thinking mine is blue 18 tooth but faded due to age?
