I have a 1998 Ford Expedition with a Python 700 2-way system. I've installed the system and all the "alarm" functionality works fine. The problem I am having is with the door locks and the dome light supervision. The system has built in relays, and LOUSY instructions. The system has the following wires:

H3/A - Domelight Supervision Relay Input #87 - BLACK/ White
H3/B - Lock #87a Normally Closed - WHITE/ Black
H3/C - Lock #30 Common (Output) - GREEN/ Black
H3/D - Lock #87 Normally Open (Input) - Violet/Black
H3/E - Unlock #87a Normally Closed - BROWN / Black
H3/F - Unlock #30 Common (Output) - Blue/Black
H3/G - Unlock #87 Normally Open (Input) - Violet* (Common with H3/D at fuse holder)

and

H1/9 - Domelight Supervision Relay Output #30 - This wire is ALSO BLACK/ White and has a note in the manual that reads: If the input wire H3/A is not connected there will be no output on this wire.

I have identified the following wires in the wiring diagram and have found them in the vehicle:

Power Lock - Pink / YELLOW
Power Unlock - Pink/Green
Lock Motor - Pink/Black
Domelight Supervision - Polarity Positive - BLACK/ Light Blue

I have a multimeter and I verified everything I've installed so far. My problem is the installation instructions for this portion do not tell me what to expect from the wires I've identified, or what the system will be doing to the wires once hooked to them. The other wires were easy because the expected behavior of the wires was obvious (12V Constant, Ground, - door trigger, etc.). These are not so obvious, at least to me, and I don't know what the system itself is doing to these wires, i.e. what is Lock #87 Normally Open (Input)? What kind of input is it looking for? That's what I'm trying to understand.

I've tried connecting H3/C - Lock #30 Common (Output) - GREEN/ Black to Power Lock - Pink / YELLOW without cutting Pink / YELLOW and connecting H3/F - Unlock #30 Common (Output) - Blue/Black to Power Unlock - Pink/Green without cutting the Pink/Green wire, but the locks still don't work.

I'm also thinking of connecting H3/A - Domelight Supervision Relay Input #87 - BLACK/ White to 12V and H1/9 - Domelight Supervision Relay Output #30 to Domelight Supervision - Polarity Positive - BLACK/ Light Blue to make the domelight work with the remote, but I'm not sure that's correct.

Can someone please point me to a diagram or describe the correct connections for this?

Thanks!

Alarm GREEN/ black to pink / YELLOW of car
Alarm blue/black to pink/green of car

All the above will be in the install manual for the alarm, type "B" locking, please read the install manual.

Do you mean H1/9 to vehicle BLACK/ light blue?

Thank you very much!  The installation manual that came with it is very vague on connections.  It's written for professional installers so it doesn't really spell out where to hook anything up, it just identifies the input and output wires on the unit.  I went to their website and emailed them.  Their response was the system was not meant to be installed by anyone other than approved installers, and that they would understand the manual.  I understand the reasoning, keeps the reputation for reliability high and protects their client network, but I was given the system as a gift and can't afford to have it professionally installed.  I really appreciate your assistance!
