im completing my motor swap in my new 87 4runner, 22re, i took it all apart and now i cant figure out where these hoses plug in.
in the second picture i've plugged the oil pressure sensor into the matching wire from the engine harness, but i dont have another plug hanging around to plug into the AC compressor.
if you could help tell me where these hoses plug into, thatd be awesome
thanks

Your first picture is to your crusie control and I have never had one so cant help on that.

Your second picture, the wire should be attached the harness coming off of your fuse box and I believe drapes over to the Intake. See if you have a single wire that is broken off of the harness.

The third picture is coming up saying it has been removed.

Cruise plugs into the black plastic 3 nipple vacuum thing towards the back of the intake manifold.

Third picture is your fuel return line. It connects to the fuel pressure regulator at the back of the fuel rail.

From what it looks like and I agree with arlindsay that is the Fuel Return Line. It should come off the rear of the Fuel Rail and connect to the metal Return Line. On 87 I am not sure if they put it on the fire wall or next to the charcoal canister, (Usually on firewall).

It is still hard to tell by the picture, but if that is the correct hose and you start it, you will have a massive fuel leak. That is one way I check to see if I am getting plenty of fuel is by pulling that hose off the firewall and running the hose into a can.

Since you are working on that hose and while you are in there, I would suggest checking the Return Line. Most of them I run into are clogged. I remove the gas cap and with LOW pressure air, I pressurize the metal Return Line to see if it is clogged. If it isnt clogged, you will hear the gas bubble in the tank. Using high pressure I am afraid will compress the clog.

If it is clogged, I use a gear oil bottle lid as a funnel and fill the line with Marvel Mystery Oil and let it start soaking it way to the clog. It can take a few days to work the clog out. May be more info then you wanted but just to make you and others aware of a possible problem. It just takes the strain off of the fuel pump. It will run with it clogged, I have seen many of them run with clogged return lines.

Well thanks for the help everyone, I found a home for all those loose hoses. Truck fired up! Has a bit of a stumble at idle though, what would the symptoms be of a clogged return fuel line? I'll have to check that thing for clogs

You wont get any air flow thru it. I have seen trucks with clogged return lines run great. I feel it just adds stress on the fuel pump.
