Can I bypass the headlight dimmer switch on the steering column and and replace it with a dimmer switch in the floor on my 88 Isuzu?

It can be done if you have the wiring diagrams.
I do not know if the information is available in our database and I need more niformation on the truck model to find out.

Yes headlights and taillights can be turned on and they work fine- I just can not dim the bright lights(as the dimmer switch won't click)
I would like to put one of those floor dimmer switches in because a new one for my steering column costs 195.00 and my funds are not good at this time(laid off almost a year now) if you can help us with this you it would be so good. Awaiting your response.

Thanks,
Shelly

Under present conditions, when headlights are turned on, the RED/BLACK wire is being grounded to turn the HIGH beam on.

You would need a 2 way switch to operate the system. Ensure the floor dimmer has 2 way functions.

At the headlight switch wireharness, cut off the RED/BLACK ( high beam) and RED/Yellow wire ( low beam). The RED/Yellow wire FROM switch is not going to be used so you need to insulate it properly and tape it back to the harness.

Floor dimmer switch should have 3 terminals for Low, Common and High respectively.

The RED/BLACK wire coming from the headlight switch would be the common ground for both circuits.

For LOW beam terminal at FLOOR DIMMER switch, attach RED/YEWLLOW wire going to fuse box.

For HIGH beam terminal at FLOOR DIMMER switch, attach the RED/BLACK wire going to fuse box.

Ensure the floor dimmer is located at an appropriate position before securing it.

You are set to go. Test if system operates correctly.
