How hard is it to add a throttle trim switch for the drives? Is there a kit? right now it has the standard drive trim switches on the dash......99 38 scarab. thanks

You can get an add on switch. Its not that difficult to do as long as you have access to the back of the dash switches. You just need to wire in isolators so your right and left dash switches still work independently.

Where is a good place to get this stuff?
