I picked up a 95 integra with a Full ITR swap and it looks like the previous owner just used a jumper with the existing harness and ran the addition wires. How can I read codes without a obd2 port? Will the obd1 paper clip trick work with the same PIN numbers using the jumper harness? Can I read them from the ecu? Searched around a bit and I don't see much on reading codes with a jumperd loom.

Also my vss isn't working because the wires were under tension and appear to have pulled from the plug. Would this keep vtech from engaging? The car seems somewhat slow and I don't feel any hit like I do with my s2000

 

VSS code will disable VTEC. Yes the paper clip trick will work

 

Thanks a ton. I appreciate it. Didnt want to go and jam a clip in the obd1 port and smoke some electronics. I figured VSS was used for vtech but a few post on here hinted at the opposite.

Wish me luck on my junkyard hunt for a new VSS harness side pigtail at the UPullIt.

 

They're a dime a dozen. Plenty of other sensors on accords,integras and civics use the same connector if you can't find a "VSS" connector.
