coolant temp wiring
2 Attachment(s)
I am trying to set up a k20 conversion harness for an 01 I sight. I've done cluster swap for it and based on the diagram coolant temp signal is a4 @ cluster. light green wire. I assumed it was on the engine harness that provided signal through the chassis connection. but I guess I was wrong and forgot to grab that plug from a wrecked insight. I have the complete engine barness so I was able to trace it all out.
but I can't find the coolant temp signal from ecu to cluster. I have the rest pretty much figured out. |
Re: coolant temp wiring
On my swap an 04 TSX engine the engine coolant temp is on the CAN bus between cluster and ECU.
I am not certain but I think most of the K stuff the temp is on CAN bus. So you could convert CAN bus to a voltage with something like Arduino or install another temp senor in the head for the cluster to read. For the real advanced the 06+ S2000 cluster gets its coolant temp from a serial interface between ECU and cluster. |
Re: coolant temp wiring
my rdx is the same but the temp fees comes direct to cluster. if there was a comm wire to the mcu (multuplexer) then yes. but here it's direct connected to the cluster.
I tried joining insightcentral.com but can't for some reason. I will recheck the shop manual tonight, hopefully I missed something easy. |
Re: coolant temp wiring
I found it. was able to source out the ecu pinouts and full service/shop manuals.

Glad you got it sorted. You should post up what the engine came from and what pin is missing to help the next guy out. |

mianly wanted to join because in a search it said the service manual was stickied. lol
