I recently bought a 1987 Jeep Wrangler with a 4.2 liter 6. Comming from the transmission, there are four color coded hard plastic vacuum lines. They are coded red, green, yellow and blue. These vacuum lines pass under the battery, on the passenger side, and appear to go to the front axel shift motor.
Close to the front passenger wheel (still inside the engine compartment) these four lines have splices in them. The yellow and green line are spliced color to color and are connected to the front axel shift motor. The red and blue lines are disconnected at the splices. The problem is, there isn't a red and blue line connecting to the shift motor. There is instead another yellow line and a black one. In essence, on the transmission side of the splices, the colors are red, yellow, green and blue. On the axel shift motor side of the splices, they are yellow, yellow, green and black.
Does anyone know what is the purpose of these lines, how they work, how they should be connected, what the vacuum source is? Also, because of the difference in colors, is there a component missing?
Also, from the transmission, there are two other ordinary black rubber lines. These go up and are just attached to the firewall with a plastic clamp. Both of these hoses have a white plastic cap in the end of them. Any ideas of what these are for???
Thanks ahead of time for any help.
