Installing and Connecting the Electronics
Installation of the electronics is primarily a matter of plugging connectors together
as per the arrangement determined in Planning Your Installation:
NOTE: While connecting ECU, nodes, harnesses and sensors, mark each item to make it easy
to identify and configure in the app at a later step.
1.
Connect each product node to a product node harness. (Select 16CH or 4CH
harnesses based on your original installation plan.)
2.
Link the nodes together in a daisy-chain by plugging the female 8-pin Deutsch
connector of the first node into the male 8-pin Deutsch connector of the
second, etc.
SUGGESTED BEST-PRACTICE: Label each product node with the number of its
sequence in the chain (Suggestion: use a mark-all marker).
NOTE: 4CH node harnesses are compatible with 16CH node harnesses (and vice
versa).
3.
Connect the ECU’s 8-pin female Deutsch connector to the 8-pin male Deutsch
connector on the harness plugged into the first product node. If necessary, use
an ECU to node extension cable. (If using a ECU Y-splitter cable, reference
Appendix 1).
4.
Connect an 8-pin ECU terminator to the harness on the last node of the chain.

5.
Connect sensor cables to node harnesses. (Single sensor cables to 4CH node
harnesses; quad sensor cables to 16CH node harnesses.)
6.
Cap off any unused node connections to avoid possible corrosion of terminals.

critically required for proper flow
readings in the app.
