Night Devil Posted September 7, 2005 Share Posted September 7, 2005 Hi. I'm looking for 4x4 pick-up (1992 model !!!) chassis wiring diagram. (yes, I know it's a rare or not exist model in the US). I reckon it will be similar to a 1984 DL. I just bought the Hayens manual but it will take up to 10 days until it will be here, at Israel, and I want to fix it. The problem is the lights within the cab. When open the doors it won't turn on. The indication at the gauges works just fine, but no 12v fit reach the light. I want to follow it to it's source... thank Ezra Link to comment Share on other sites More sharing options...

Night Devil Posted September 7, 2005 Author Share Posted September 7, 2005 night, is that a twin carb ea81 in that truck??? Nope. EA81 with single carb, as far as I know... 1800cc, manual, 4x4 this is it (before the present reconditioning) : Ezra Link to comment Share on other sites More sharing options...
Ross Posted September 7, 2005 Share Posted September 7, 2005 If i remember correctly, the wire for the light runs across ro the front to the drivers A-pillar (which is right hand side in my case) and down there - you can see it with the trim off.

Cougar Posted September 7, 2005 Share Posted September 7, 2005 If you have an overhead map light I would check up in there. I have heard of problems in that area. Link to comment Share on other sites More sharing options...
Hondasucks Posted September 7, 2005 Share Posted September 7, 2005 Check the light itself, Not sure about yours, but mine has a switch, one position leaves the light off, one leaves it on, and the third makes it coem on when you open the door.

Night Devil Posted September 8, 2005 Author Share Posted September 8, 2005 well... after "digging" in the wiring loom I found the problem. Possibly the previous owner try to fixed a problen and create a new one by connecting the wires wrong. What I got was 3 wires and I knew that one of them is 12v, the other is body ground, but the third was uncertain. I couldn't even tell if it suppose to be ground or 12v. and further more, I was curious... how is it, that each door is distinguished on the gauges panel but not by the cab light ? So... yesterday I was... a man on a mission !!! Each door switch connect the body ground to the gauges. Each door lights up different hazard signal (left & right), so the gauge "need to" distinguish between the switches, but the cab light "don't care" which door is open and need to lights up in any door opening case. so basically, the cab light gets 1x live feed 12V and 2x ground feeds. choosing the "correct" ground done by the switch on the cab light. One ground is directly from the body (fixed light on), and the other comes from the gauges, after collecting both switches (4 switches in case of sedan) by a technique called in electricity "power or-ing" which done by diodes. (those diodes are part of the gauges circuit, and if its intersting anyone, I will be more detailed about this simple technique). first time for me to see such system at car, and glad to find it after 3 hours of searching wire colors at my current dismantled cab. a repair manual with color wiring diagram could've been great. Thank you all for your attention and help. Ezra Link to comment Share on other sites More sharing options...
Ross Posted September 8, 2005 Share Posted September 8, 2005 a repair manual with color wiring diagram could've been great. Yeah, but even if you can find one, the colour lables are sometimes wrong anyway!! Link to comment Share on other sites More sharing options...
