gotta few bugs i need worked out on my 88 dx crx.
my fuel gauge, brake lights, reverse lights and tach are not working. maybe sumone can direct me down the yellow brick road...

ive put new bulbs, and replaced the brake light switch (used). i put a test light on the 3 wires of the brake light switch and they were dead. is it possible i got another dead brake light switch ?

i think there is a harness off the gsr hydro tranny that is not plugged in. is that y the reverse lights are not working ? how can that b fixed ?
lmk about the other stuff if u can. thanx

is there a sensor for the fuel tank. is it a fuel sending unit ???

where do i begin on the tach ???

lmk guys and gals !!!
