Ok so I'm assuming this hose should be one continuous hose its to the heater control valve its broke in two and one end is taped up?

This one is open and have no male plugs within reach of it, is it for emission tests?

This one is on the passenger side also with no connecters near it?

I've searched online with no prevail so hopefully they are nothing important

 

Is it 87-88?

 

The first one is definitely an issue I would fix it asap. The second one should go to something but I'm not sure what I don't think there are ever open connections on that side of the motor. The third one is probably nothing but once again not positive. I haven't been in a renix in a while so hopefully someone with a renix will chime in and help clear things up a bit better for you.

 

its a 90 flintstone, ill connect the pink hose together and hope it helps with my in cab heat

 

Lol. yea, that would help. That looks like a CPS connector. Sometimes the C101 connector on the earlier get's bypassed and it's plug might be left. If your CPS doesn't have a plug that's probably it.

 

I've just recently replaced my cps sensor so i know that's not the plug for it im just stumped :/

 

I'm still wondering if it was for the CPS.
In the instructions for installing a different harness, it says to "cut off the old wires to the loom"

It sure looks like a CPS connector to me, I just kept my mouth shut cause how the hell would it even start without it connected? I think Flinstone is right on this one.

 

I've got an 89', and I've got that open connection regarding your third picture as well. It is a hot wire (Not sure if its switched or not). I have nothing that doesn't work, and can't find anywhere for it to belong... I wouldn't worry about that third one.

 

If your rig is running fine despite those last two open connectors, don't worry about them. I'd just plug them up with silicone to keep ém clean and try to keep them away from close contact to any heat source. Chances are, they're probably not needed otherwise you'd have had some issues you would've posted along with the lingering doubt as to what they're for. As for the pink hose, you're probably on to something. It might be a vacuum line that helps control the gates for cabin temp.
