Hello,
I've recently noticed two unplugged wires (pictured below) near my headlights towards the front of the grill where the factory mounts are for spotlights. I am curious if these are indeed spotlight wires, and if so which spot lights would work with the plugs? If not then I am curious what they could be for?

I have also noticed a warning light (pictured below, handbrake pulled to trigger light) comes on temporally when I accelerate and turn but after 2-3 mins of driving it will no longer turn back on when accelerating or turning.

Also my RPM gauge doesn't show the RPM until 3-4mins of driving, its like it needs to "warm up" where it'll get stuck at 2k RPM and then if i accelerate to 3k it will get stuck there until it starts to function as normal after driving for some time. My fuel gauge is also showing incorrectly but I have ordered a new fuel sender and will be replacing it soon. None of my fuses look blown but i lack the proper tool to test them. Any input or help is greatly appreciated. Thank you and have a good one!

Those plugs you show are indeed for factory fog lights, the wires are in place on all models but only those originally equipped had the switch in the dash.

Three things can trigger the brake warning light: pulling the handbrake, low vacuum, or low brake fluid level. Given that yours only comes on during acceleration and cornering I would suspect your brake fluid reservoir could stand to be topped up.

Thank you for the reply! I’ll top her up. Have a good one!
 
Follow up: After topping off the brake fluid the light no longer shows up after turning/ accelerating. Still no progress on the RPM gauge. I suspect it may be a old relay that needs replacing.

Thanks for the great info here! I am having the same issue with my KZJ78. What type of break Fluid did you use to top it off? Thanks!

Hello, attached is a helpful graph I found for the KZJ78 regarding fluids and levels. I hope this helps you in the future. Sorry for the late reply
