The CAN harness attached to the dash includes both male and female CAN connectors. These connectors are
wired in parallel to allow daisy chaining of multiple devices on the CAN bus.
Note that the Pro Dash does not use the CAN cabling to supply power and ground for it, unlike some other
Holley EFI CAN devices, nor does the Pro Dash supply power to the CAN cabling, which is provided by the EFI
harness.
Pro Dash CAN Cable Description
Pin Function Description
1 +12V Power (pass through between connectors, not used for Pro Dash)
2 CAN1H CAN_H Holley EFI communications
3 CAN1L CAN_L Holley EFI communications
4 GND Ground (pass through between connectors, not used for Pro Dash
CAN Extension Harness
The dash is supplied with a 4’ CAN extension harness. Holley also offers the following replacement harnesses:
558-451
– 1 foot
558-452
– 4 feet
558-453
– 8 feet
558-454
– 12 feet
Additional wires can be installed to use additional functions in the Pro Dash. Consult the connector diagram
and main user manual for more information.

Notes:
1. The 12V main power input (pin 2) also provides backup for the internal clock and GPS.
2. IGN (pin 25) needs to be connected to 12V to turn on the unit (low current input).
3. SSR1-SSR4 are low-side solid state relays, 1.5 Amp max.
4. 5V_EXC is used to power sensors, 450mA max.
5. CVBS inputs are reserved for future use.
The unit will draw approximately 5 mA in standby to maintain its real time clock and GPS information for quicker
acquisition.
