86:
Connects to the
Ground Out when Running
wire from the remote start module. This becomes
the negative side of the coil.
87:
Connected to a Fused +12 Volts source, that is capable of supplying power for the vehicle's
second ignition wire. This becomes the source of power for the 2
nd
ignition wire.
87A:
No connection. This terminal is not used in this application.
30: Connects to the vehicle's second ignition wire.
This becomes the output
of the 2
nd
ignition relay.
Comments: The relay is only energized when the vehicle is running by remote start. When started
with the Key, the relay is not energized and the integrity of the stock system has been preserved.
Isolation:
Example: Isolating a Park light output
Problem: Some vehicle circuits need to be isolated from feedback. In some cases, when a vehicle
is remote started, feed back occurs on a circuit, and powers another device or switch, that was not
intended to be powered during the remote starts.
The following example will be a Positive (+) Park Light circuit that feeds back and activates the
windshield wipers during remote starts.
Solution: When power is applied to the OEM Park light wire it back feeds through the park light
switch, and activates the wipers. Where the connection was made from the start modules' Park
light output, and the vehicle's park light circuit, the OEM park light wire is cut to isolate the park
light switch and the actual parking lights. A Relay is added to the park light circuit so that power
from the remote start module is only sent to the parking lights and not the parking light switch.
The relay connections:
85: Connects to the +12 Volt Park light output from the remote start module. This becomes the
positive side of the coil.
86: Connects to a Negative source. i.e. The spot where the remote start module is grounded. This
becomes the negative side of the coil.
87: Connects to the +12 Volt Park light output from the remote start module. This becomes the
power supply for the vehicle's park lights.
The OEM park light wire is cut. The side that is still connected to the switch becomes the “Switch
Side”. The side that is still connected to the Parking lights becomes “Parking Lights Side”.
87A: Connects to the “Switch Side” of the cut OEM park light wire.
30: Connects to the “Park Light Side” of the cut OEM park light wire.
Comments: When the relay is at rest, the OEM Park light wire is connected (through 87A & 30) and
allowed to operate normally. When the remote start module powers the Park lights, the OEM park
light wire is opened, and power from the remote start module is sent only to the actual Parking
Lights ( from 87 through 30).
