Dear Forum I have a Peterbilt 320 from 2007 (Paccar- Mexico) - ism 350 and this car is working in PAnama (it's the only model here) (i have no official dealer). I had a problem with the warning light (humidity or some electrical problem that i don't know) and the result was this... Now i bought a new one adn some new wires with different codes but unfortunately i don't know the wiring diagram....this warning module has 4 inputs (the one that has 6 pins is for speedometer i think)...the speedometer burned with the short circuit. Now comes my doubt: each gauge has 2 inputs...my idea is; 1 - module - rpm - temp (cable code)? 2 - module - oil temp - pressure? (cable code)? 3 - module - air tank 1 - air tank 2? (cable code)? 4 - module - Speedometer - diesel tank?...it is possible to connect this 5 pin gauge to the other input of speedometer? (cable code)? Thank you so much for your time and attention reading my problem BEst regards Xpander
