Help With Relay Wiring!

Ok, I am hooking up a remote start system on my truck. It shows that in order for it to work with a manual, you must use a relay on the clutch switch. It even gives you diagrams for that relay. However, it has two diagrams, one titled open circuit clutch switch, and one titled closed circuit clutch switch.

On the Open Circuit Clutch Switch it has the following connections:
87: One wire from clutch switch
30: Other wire from clutch switch *(Pins 87 and 30 have no polarity, connect to either wire from clutch switch.)
86: Connect to ground when running output (goes to remote start box)
85: 12 Volts
87a: Nothing

On the Closed Circuit Clutch Switch it has the following connections:
87: Nothing
30: Connect wire coming from OEM clutch relay (cut after relay and connect the other wire to 87a)
86: Connect to ground when running output (goes to remote start box)
85: 12 Volts
87a: Connect to wire after what you cut coming from clutch relay.

My question is, what type of circuit do the Rangers use on the clutch switch? Do I need to wire the relay up as Closed Circuit or Open Circuit?

Same with dome light, it has a hook up for dome light on the computer for the remote start, it shows two different relay wirings, one for Positive Dome Light Activation and one for Negative Dome Light Activation, which one do I use? Only difference on the dome light wirings of relays are one switches the relay for 12 volt (Positive Activation) and one switches the relay for the ground ( Negative Activation).

Help very much appreciated!!!

for the clutch the rangers use a normally open circuit so the first setup you listed is correct. I don't remember what the dome light setup is.

If its the same as a 2001 then its a normally open switch. Should have two wires, a WH/PK wire feeding 12V to switch with ignition on and a PK wire going to the starter relay in the BJB.

Wire relay for Open Circuit Clutch Switch
87: One wire from clutch switch
30: Other wire from clutch switch
86: Connect to remote start box
85: 12 Volts
87a: Blank

Does the instructions say to install the relay in Parallel or in Series with the clutch switch?

The door switches are a negative trigger (ground) to the GEM which in turn controls the battery saver and dome light relays on 2001.

87: Ground
30: spliced to door switch wire (can be done at GEM on 2001)
86: Connect to remote start box
85: 12Volts
87a: Blank

This would simulate a door opening turning on the dome lights.

Only thing is, I am 2005, so I don't believe I have the GEM. I have the SJB (smart junction box) in the passenger side kick panel.

Instructions do not specify parallel nor series as far as the relay is concerned.

The 2005 clutch switch is normally open as in previous years and the color codes are still white/pink and pink.

For 2005, the door ajar switches are still electrically open when the doors are closed, grounding when they open (negative trigger). The color codes are unchanged too: yellow/black for the driver door only and gray/red for all other doors. They ultimately end up in the wire bundle at the SJB but it might be easier to pick them out at the plugs under the kick panels where the door harnesses meet the dash harness.
