flickering display
Well, I tried to stop the flicker today. I spliced into the ambient sensor wire (black and white) and tried to ground it inside, since I can't seem to locate a hole through the firewall unless I make one. Alas, I grounded it on a bolt for the dashboard brace. The flickering is still present. Can anyone recommend an access through the firewall??? Do you guys think that this ground on the brace is actually working??? :banghead:

Since the car is glass a ground is hard to locate. You need a test lamp.
Any auto parts store will have one. The cigarette lighter has a ground.
Flickering display, on my L-98 it was a bad ground. It didn't flicker so much as it would go blank, hit a bump and on it came. The LCD has a ground that after time corrodes and it becomes intermitent.
A good manual will show the location of the ground. Helms is the best one.
I never repaired mine I just slapped the dash, and after a season sold the car.
Also you can locate a ground in the fuse block.
To test a ground hook one clip to a hot wire and the other to the ground.
If it lights the ground is good.

Re: flickering display (redwing76)
When I did the ambient sensor ground thing-the black and white wire, I took a piece of bailing wire-slipped it through a small hole from the engine compartment, taped the wire on and pulled it back through,grounded it to the frame-there's a ground next to the battery, cleaned it and attached it there. I don't think you're getting a good ground at the dash.The main ground for the harness is next to the door hinge pillar post on drivers side-my way seemed much easier. You may need to pull the cluster and clean the connectors-no big deal :thumbs: Most cluster rebuilders will piggy back the three grounds within the cluster-I can explain it but soldering is not my thing ;)
