RB30 Trigger Information
Sensor Information
Distributor
These engines come with a Distributor.
An optical Hall Effect style trigger is used. It has a dual sensor element that reads from an outer 360-slot section and an inner 6-slot section (one for each cylinder). The 6-slot section has 5x slots that are the same size, and 1x slot that is larger and is used for engine sync. The ECU looks at how many outer teeth occur during each of the 6x slot intervals and uses this to start the sync for Cylinder 1.
Wiring
| Pin | Description | Haltech Connection |
| 1 | Signal Ground | Blue (Trigger 4-core) |
| 2 | 12V+ Switched | Red (Trigger 4-core) |
| 3 | 360x (Home) | Home+ Yellow (Home 4-core) |
| 4 | 6x (Trigger) | Trigger+ Yellow (Trigger 4-core) |
Trigger and Home Wiring Hack
A common hack to make wiring simpler is to do the following:
In the Grey shielded Trigger 4-core cable we have 12V+, Signal Ground, Trigger+, and Trigger-. We need all of these wires except for Trigger-
In the Grey/Black shielded Home 4-core cable we only need the Home+
If we relocate the Green Trigger- wire so that instead of going to this ECU pin it instead goes to the Home+ ECU pin we now have all of the wires we require in a single 4-core cable.
For Elite 550 / 750 / 950
1. Remove the Yellow wire from ECU pin A32 and insulate it. It will not be used.
2. Remove the Green wire from ECU pin A33 and move it to A32.
For Elite 1000 / 1500 / 2000 / 2500
1. Remove the Yellow wire from ECU pin B2 and insulate it. It will not be used.
2. Remove the Green wire from ECU pin B5 and move it to B2.
