Installed these with new glow plugs and one of the connectors was loose. Only time will tell if this will be an issue.

Some one told me don't use cheap ones. So I bought NAPA best line. It was the cause of weeks of diagnostic work and wasted money. Two of the injector pins were getting continuity, injector #3, power was 0 ohms to the ground pin to signal voltage. Went to the local NAPA and he pulled every one in stock, they were all bad! These from RR saved me and had less resistance than the Dorman's I tried as well.

Perfect fit on these International parts. My harnesses finally came loose so I ordered these and replaced both sides. They fit perfectly. I highly recommend these OEM parts.

Replaced with my injector rebuild

Local dealer only had one in stock and said it would take another 3 days to get another. Ordered overnight from Riffraff, came in on time, and is an exactly the same piece as from the dealer, just way cheaper. You guys are my new power stroke go to shop!

Did not realize harness was made in China, but maby that is where the OEM, harness is made ?? fits as should..

Although the UVCH fit as it should and looked to be of good quality, I was disappointed to see that they are "Made in China"

Excellent service, quick delivery, exactly what I ordered!
Thank you so much!

Don't install those non oem product I was chasing p1316 code for a while I pull trigger and replace the gaskets and harness glow plugs before I decided to replace the IDM problem fix.
