Product knowledge test, unknown wire and vacuum line

[airspeed]

Starting to put the engine bay back together and have one red wire ~ 10-12ga. single spade connetor and a blue vacuum line. Where do these go? See photo. This is and 88, 2.5, 4spd, no A/C[http][imghttp][/img][/img]

Fixed the pic for ya

 

The red wire I believe is for a factory hood light. The blue vacuum line could be for cruise.

My hood drop light has a two pin connector, but it came from a newer Cherokee?

Blue vac hose is a bleed/vent. Leave it lay where it is. Where does the red wire go to. Being 1-12 ga it must run something like an added on accesorie. Fog lights maybe. Follow the line to find out.

The heavy red wire goes back through a fuse link to the silver relay where the battery is connected. There are a group of 4 ring terminals that share the post on the relay. I will use it to run my hood light.

The heavy (8 gauge) red wire, if it's spliced to the blue fusible link, goes to the alternator. It's not a spade connector in the stock condition, but may have been changed from a ring connector if a different alternator was installed. Just make sure you do have a wire running from the alternator "battery +" terminal to the stud on the starter relay before you decide to use it elsewhere. :D The other 8 gauge red wire on the stud goes to the positive battery terminal. You can always run an additional wire off the starter relay stud for your hood light (might want to inline fuse it) and it won't need to be nearly that heavy a gauge for the light.

The red wire is 12 Ga and it is for the hood drop light. It's grounded thru the hood. There will, or should be a strap by the right hand hood hinge. One end attached to the firewall and the other to the hood side of the hinge.

Yep, on second look at the picture, it sure doesn't look any bigger than 12 gauge. Probably doesn't go to the alternator. But there should be five ring connectors total on the stud terminal of the 4.0L starter relay; one 8 gauge red to the battery, and seven fusible links divided among the other four connectors. My point was that all these links are spliced to a red wire that is designated to go somewhere, e.g. alternator (spliced to blue link), fuel pump relay, TCU, & ECU (all on one orange link) B+ latch relay (orange link), fan control relay (green link), ign switch (green link), and BINGO....fuse box and underhood light (on one green link). :yes: According to the wiring diagram, this one is a 14 gauge wire.
