On my car, a 1991 Benz 300E, I have two different connections for door triggers at the alarm. One is for the rear, and the other is for the front. They Both show (+) when closed, and (-) when open. To connect both these wires to the single input on the alarm, would I use a pair of diodes? If so, how many amps (I have a pair of 6 amps left over from parking lights)? And last question, would the stripe be pointed at the alarm or at the triggers?

The vehicle should have vacuum locking and you will need to follow the above diagram to hook up locking ther should be a blue or green wire going to the vacuum pump witch is located under the rear seat you will have to cut this wire and place it in the circuit as illustrated. ( this wire will show a 12 + on lock or unlock but will show a 12v - in the opposite state. The alrm or keyless entry system you are fitting must have a selection to have a neg pulse of at least 2 seconds , if it doesn't you will have to place some kind of timer into the circuit. ------------- ozy installer

I'm sorry if I confused anyone, I meant the Door Pins, that show a (-) When the door is open and a (+) when they are closed. I have 2 different wires, one for both rear doors, and one for both front doors. I was wondering how to connect them to the single input on my alarm module.

They are (-) negative trigger........The reason it shows + when you close the door is because it is feeding off the other half of dome light which is the + feed
Hook your Door Pin wire from Alarm that is Negative trigger

I know, but I have two separate wires, not a common wire for the door pins. One wire for both rear doors, and one for both front doors. I only have 1 input on the alarm, but two outputs from the door pins. I know if i just twist these together and connect them weird things could happen, so do I need to use a pair of diodes? If So, what amperage ( I have two 6 amps left over from parking lights). THANKS!

Put the stripe facing the door trigger wire. The side that is striped should be closest to negative triggers.
