95 volvo 940 - Need to identify these wires
 

The pictures shows to wires, one orange reddish, one yellowish. I noticed them when I bought the car, which runs great, but I'm wondering where they go to and what they are so I can have them repaired...

They are located toward the front of the car on driver's side... they run up toward the front headlight area

Did they have fog lights before?

Outside Temperature sensor?

Could be, but I thought those should be in the space above the wheel well...

per the greenbook for a 1992 940, the fog lamp wires are white-black and black (my 92 has the wires even tho it doesn't have the foglamps)

odd, that doesn't really look like volvo wire loom, it looks like the aftermarket stuff. in your pic, the wires look to be green-red and green-white or green-yellow.

looking at the wiring harness connectors on my 92 740/940 greenbook, gn-w is used for lowbeams, its also used for the engine temp sensor for the EFI. and for one of the loud speaker circuits (that sure doesn't belong under the engine!)

green-yellow is used in the EFI harness...

green-red is used for the fuel injectors, power windows, door warning lights, a/c solenoid coupling, a/c high pressure sensor...

FRAPPE. I might be mixing up green and grey (GN and GR in these green-books).

if you could better identify those colors, would help so I won't be shooting quite so blind. need to know the wire color and stripe color, like when I say green-red, thats a green wire with a red stripe. red-green would be the other way around. your picture isn't clear enough.

and oh yeah, my book is for a 92 740/940, its quite possible that a 95 has some differences.

oh, look what I found. 1995 940 ... optional "Parking Heater" (this is a gas fired heater, which has its own fuel pump, lives under the hood, and is for those freezing cold northern european winters....)

note the item 5 on there has gn/y and gn/r wires to it. 'thermostat'. another diagram showed this behind the front airdam about 1/3rd of hte way over from the left headlight.....

*bingo*.

So what would you hook those wires up to?

The heater so the car can tell it when to turn off?

um, IF those are for the optional parking heater, and you don't have that parking heater, they are hooked up to nothing. the parking heater is used to preheat the car when its really really cold out, its hooked up to the coolant, and has an electric water pump and a gasoline fired heater, and a timer... when the timer turns it on, and its cold enough, it heats the coolant, pumps it through the engine and the heater core in the passenger compartment, and also turns on the fan to blow warm air into the passenger compartment, so when you wake up and have to drive to work, your car is toasty.

Out here in California, I've never seen a parking heater in _anything_ except this one 1968 VW converted to a "Baja Bug" I bought off a guy who used it for hunting, he had installed one because the stock heater was hopelessly inadequate in high mountain winters.

Parking heaters are big here in Dallas! We call them bar-b-que grills though.

But if you did have that option, what would those wires be connected to and do?

there are a number of wires in the harnesses on the 740s and 940s I've seen that are for optional accessories. for instance, my 740 that has the single headlights has all the wiring for fog lights. it has no door speakers, but the wiring is in place for them.

Yeah, 240's have the fog lights too. Same with the Tach wires in the instrument cluster when there is ALWAYS a clock there :mad:. I'm curious to see if they have the seat heater harness, as mine did not have that option. That would be great so I can jimmy this aftermarket switch to it so I can connect it to an original seat heater switch.
