I dont know the exact color code for your vehicle or where they connect..
but if it is a 3 speed motor,
1. BLACK is ground
2. Blue is one speed.
3. RED is another speed
4. GREEN is another speed.
What I did once was to throw the black to ground, and connect one of the other color wires to the wiper...
(normally..i dont understand that there isnt a connection plug
that has 3 or 4 male pins..in it to the wiper motor...but anyway):
Figure out first what number of speeds the old vehicle the motor came off of...this will let you know if it is actually a 3 speed motor.
You may have to worry that your wiper switch in your vechile only goes to low and high speeds with one off . (Off/Low/High).
OK>.. run black to ground..(have a few extra fuses around.)..
grab the green wire and put it on a fuse side //left or right of the fuse..and be sure the fuse you are using will go dead when you
shut off your ignition key..(never want active wires when vechicle is off). I would suggest you find the HOT side of the fuse in your vechicle by taking the fuse out, turn your key to RUN, and go down and meter one side of the fuse post at a time...find out what SIDE the fuse holder is hot...the other will be dead...ITS THE DEAD SIDE YOU STICK YOUR new wiper wire to..this way..the wiper motor can use the existing fuse..and it will blow if the wire to the wiper motor shorts somewhere along the way past the fuse connection you are bout to make....or you can put a fuse INLINE in that wire, and wont have to do the above test..
both will work..so lets get on with this:::::::::
Turn key switch to run....(not start), and turn on your wiper to low...then to high..if it works ,,then you have found either the low or high speed side of the wiper motor...
Do the same for each wire.
I would suggest to have the motor wires connect to at LEAST a
25 amp fuse... your manual may say 30 amp.. if so..seek out a 30 amp fuse to test these wires on..\worse you can do is pop a fuse.
But if your fuse box has a fuse labled WIPER...you can possibly use that fuse.
Now..you should be able to wire up at least 2 of the wires on the wiper motor to the existing connection that fed your previous wiper motor..then just pick out the low and high feeds to the wiper motor..that is all you really should need...less u have intermitent wiper wire..you can wire that direct with an inline fuse to an appropriate fuse rated for that wire...and following the above possible wiring suggestions.
Protect your circuits..use fuses..and NEVER wire anything direct to fuse box without an inline fuse.
Worst thing is popping fuses...but it's a way to troubleshoot the back yard mechanic way.
P.s . looks like one of the wires is for the PUSH to squirt water...
so it looks like from that schematic...you have a high/low/water
switch... so it should be simple.... lemme know if you have intermitant side ok..
Keep on Jeep'n
