for an 88 gl wagon need a wiring diagram or any help with a head light that is dim on high and low beam , where is the relay fitted, any imformation would be greatly appreciated as i have already spent about 8 hours on this.

Have you measured the voltage to the lights to see what it is? I think the lights are turned on by the switch making a ground connection.
I think Sister7 may be correct about the relay location and I am thinking of something else.

If only one headlight is having a problem on both low and high beam then it may be the red/black ground wire has a bad connection to ground and is causing this problem. See if there is a voltage drop on that wire when the light is on. It should be at ground potential. If there is a voltage on it then you need to find the bad connection.
