*FIXED* loose connection down the line.

Ok. Here's the particulars: rear flashers don't work at all. Dash lights and front flashers work, but blink fast. Hazards blink at normal speed, but still don't reach the tail lights. Brake lights work unless 1) the head lights are on -- then the right one goes dead and 2) the left turn signal is activated, which makes the left brake light blink.

All bulbs and the flasher relay have been replaced (before the relay was replaced, the right turn signal stayed lit and sounded like an angry goat with a cold, so that's one problem down). Fuses are good. Grounds checked, but I might have missed one. Several months ago, the right flasher was going fast when I hit the brakes, so I suspect something's going on with that side. I replaced all the eye terminals in the tail lights about a month ago and all was good until now.

The truck's a Frankenstein monster...mostly 91 and 93 4WD pickup, 22RE engine with the tail lights of a 78 hilux (chinook mod). I didn't build it and don't know much about electrical work. If anyone has insight to what's going on, I'd appreciate it.
