7. Connectors
7.1 Relay and Fuses
All relays available in the LS Harness are fuse protected. Their max
current is 30A followed by a 30A fuse. There is a main relay for the
FuelTech units such as ECU, O2 conditioner, one relay for the injectors
and another relay for the coils.
7.2 Crank Trigger and Cam Sync sensor
The LS harness is ready to run on OEM 58x or 24x hall effect sensor
crank trigger and OEM front and rear cam sync sensors.

7.3 TPS
TPS is a potentiometer that informs the throttle position. FT500 can
read almost any 0-5V TPS. The LS harness uses a 3-way Metri-pack
150.
- Pin A: signal ground (black);
- Pin B: 5V Supply (green/red);
- Pin C: signal output (white).
7.4 H2O and Air Temperature
The LS Wiring Harness has 2 temperature inputs. One input is for
the engine temperature (H2O) and the other is for the intake air
temperature (AIR). Both sensors are GM style and uses Metri-Pack
150.2 connectors.
- Pin A: signal output;
- Pin B: battery’s negative.
