I've been seeing some noise on the MAP channel in my logs and also noticed that the TPS seems to drift a little from time to time. Tracked it back to the jumper harness, probably going to just replace it.

I currently have a Yonaka one, anyone have recommendations on a higher quality replacement? I feel like the ecu side connectors on this thing are a little janky and soft feeling.

 

I am somewhat interested in this too. I have had many different brands over the years with the most recent being RyWire. They have fallen off in my opinion and some of the better ones aren't made anymore. So who makes the best jumpers currently?

 

They all look pretty much the same from what I'm seeing. Lots of knock-off connector shells, which is what I don't care for about the one I have.

 

I think Boomslang harness are pretty good, their ecu connectors feel like OEM.

 

That's what I'm leaning toward, if for no other reason than they've been selling them forever.

I might also see if there are any obd1 cars at the boneyard if I have time to go next weekend. I'll just grab some connectors and move all of my pins over. That should lead to a Saturday of strained eyes and sore fingers, but I need to see if I can find some
CR-V knuckles for another project anyway

 

I've had good luck with Zerg's jumpers. But with any jumper it's not a bad idea to ground shield the signal wires and run thicker ground wires.

 

Go with the Boomslang. They use the factory AMP/Tyco connectors and pins with good quality wire.

 

On top of it you cant beat the price for it. I have one in my car. Very nice quality piece

 

Thanks guys.

I'm actually omw out the door now to hit the local JY. I'm gonna see if I spot an obd1 ecu harness, clip it and repin at least connector D. If that doesn't do it I'll probably go with the Boomslang, that was my original instinct anyway.

Also, anyone remember what series the OBD1 ECU connectors are in the Tyco/AMP catalog? I used to have it marked but lost it. Still have the OBD2 stuff though.
