How would you know if...

the second Ingition wire (provided your car had one) was needed for the starter.  The reason I ask is because my car has a 2nd wire, but the remote starter is already working with only the 1st ignition wire attached - it just starts "a little rough" (some sputtering).  With a key start, everything light up just fine (no sputtering).

Any thoughts?

Sorry (doh!).  Mercury Villager 1995.  Wire Diagram here:

Yes hook it up, Do you have the tach wire hooked up?

I only have one "Ignition" output coming from my RS.  Can I just jumper it to the 2nd IGN wire, or should I attach it by use of a relay.  If I have to use a relay here's my attempt at how it might be wired up (I'm really not sure but I thought I'd try after reading the "Basics - Relays" area):

30 - 12v constant

87 - to IGN 2 wire (at harness)

87a - ?? (ground)?

85 - one side of something with 12v at start or crank?

85 - other side of something with 12v at start or crank?

TIA,

Wire a relay like this:

• 85 & 87 : 12 volts Constant FUSED ( 20 amps )
• 86 : To ground out when running wire on RS unit
• 30 to ignition # 2 on vehicle
• 87a : NOT USED

Thanks Jeff. OK, I think I understand now although I'm a little confused about 86. As far as I'm aware (from my remote starter documentation), the IGN wire coming FROM my RS brain supplies 12v+ when the starter is initialized with the remote. Would this change the pinouts as follows:

• 85: IGN wire from RS (12v + when intialized by remote)
• 86: Ground
• 30: to IGN #2 on vehicle
• 87: 12v constant FUSED @ 20 AMPS
• 87a not used

Thanks, smik
