96 H1 Wait light not working

[dwaxman1]

okay weird one and looking for any advice, first of all, I have checked the bulb, (Bulb is fine) and also that there is no power getting to the plug at the dash. any idea of where the harness goes for this connection? does it goto the glow plug relay or where? I know my truck pretty good so I do not have to really have an issue with starting my truck but....it would be nice to have this working, especially when the odd time comes that someone else drives it.



I have looked at wiring diagrams but who know about them.. looking for a bit of advice..let me know please..



thanks

Check if your glow plugs are getting warm, If not, you may need a glow plug relay. Got one if you need. <img src='http://www.canadianhummerclub.com/forum ... ght_on.gif' class='bbc_emoticon' alt=':right_on:' />

glow plugs are getting warm because truck is firing up with out an issue...but I am not sure if the wiring goes direct from the wait light to the relay or somewhere else first, it is a bit of a rats nest of wiring in behind the dash..
