Just installed Hornet 554t on my 95 sentra. I didnt hookup the remote start harness though because the wire colors from this site dont match my car. How can i test the wires with a multimeter to see which is the "ignition 1" "Ign. 2" " starter" etc...?

Ignition wires show 12v+ when the key is in the Run and Start positions
Starter wires only show 12v+ when the key is in the start position
Accessory wires only show 12v+ when the key is in the accessory position
You have 2 starter wires: BLACK / YELLOW and BLACK/ Blue
Your Ignition wire is BLACK/ White
Your Accessory should be BLACK/ Pink
You may have a 2nd Acc wire as well: either Blue or WHITE/ Blue
If these colors do not match your vehicles wire harness, you may have a connector somewhere between the key cylinder and the firewall where the colors change. Follow the wires all the way to make sure. Otherwise, you can just test all of the heavy gauge wires in the main harness with a DMM as I detailed above.

Hey thanks alot J Rilla! Its been a few days but now i finally have a chance to test the wires coming from my ignition. Heres what i found: WHITE/ Red shows 12v+ in all positions Blue shows 12v+ in Acc2 BLACK/ White and Red show 12v+ in On (ign?) BLACK / YELLOW and BLACK/ Green show 12v+ in Start So i know what my wires are now yea! But i have a new dilema...I have two starter wires and only one wire in the "Relay Satellite Key Switch Interface" (remote start harness) to connect too..... How should i hook this up?!? So far ive attached both the Red wires from the remote start harness to the WHITE/ Red (12v+ constant). This is the wire i hooked the alarms power wire to. I havent attached any other wires but im thinkin they go something like this...... Pink (+ output to ign Circuit) ---->Red (12v+ in on (ign?) position) Orange (+ Output to accessory Circuit) ----> Blue (12v+ in the Acc2 position) Purple (+ output to starter Circuit) ----> BLACK / YELLOW and BLACK/ Green (both are 12v + in the start position) This is the one where im confused... Soldering the purple to both BLACK / YELLOW and BLACK/ Green dosent seem right..... Pink/White (+ Output to second ignition Circuit) ----> BLACK/ White (12v+ in on (ign?) position) Whew! well thats my current situation... If any of you pros could help guide me id be real grateful! Thanks alot!

you will probably need to relay this to get 2 starter outputs Pin #87 Fused 12v+ Pin85 ground pin 86 Starter signal (jump a wire from your alarm starter wire to this pin on the relay) pin 87a not used pin 30 output to starter

Cool thnaks for the help guys. I still have questions though.... What fuse do i need to use? Also im confused about that diagram..... If 86 is constant 12v+ and 85 is ground out, how will the relay ever switch? Should pin 86 and 85 be connected in the first starter wire? Or is jumping a wire like Swifty suggests a good way to do it?

This relay diagram will provide 12V+ to the second starter wire for as long as the remote start is engaged and should be used for an additional ignition lead, not a starter lead. If you need to provide 12V+ to two starter leads during start and the two starter leads do not have continuity or you wish to isolate them, you should use two relays. If they do have continuity and you do not need to isloate them, then you can simply connect them to the same output of the remote start. If you do need two separate starter leads from the remote start, connect terminal 85 of both relays to ground, connect terminal 86 of both relays to the starter output (+) of the remote start, connect terminal 87 of both relays to a constant 12V+ , then connect terminal 30 of the first relay to your first starter lead and terminal 30 of the second relay to the second starter lead. -------------  the12volt • Support the12volt.com

Ok so i should just use the alarm's starter output as a trigger for two relay's who will provide power directally from the battery. Still have one qusetion though..... What rating of fuse should i use? I certainlly want to be safe and not start a fire...

Use 30 amp ( GREEN ) blade fuses.

I'm guessing all these people answering your questions about the second starter relay don't install DEI remote starts. Jump a wire off the thin purple wire of the ribbon cable going to the relay pack. Connect it to 85. It is negative during crank only (it triggers the starter relay). Connect 86 and 87 to fused +12v (20 amps will be fine) and 30 to your second starter wire.
