About this product
📘 Overview
A skid steer wiring harness for the 8-pin Cat connector. The EZ Spot UR 8 Pin Wiring Harness (P-EZ-CATWH-103) connects an EZ Spot UR hydraulic function attachment to Caterpillar, ASV and TEREX skid steers fitted with an 8-pin auxiliary electrical connector. Those three brands share the connector, and it is different from the 14-pin arrangement used elsewhere in the Cat range — so the pin count on your machine, not the badge on it, decides which harness you need. A wire tool for pin adjustment is included.
⚙ Key Features of the 8 Pin Caterpillar/ASV/TEREX Wiring Harness
- Matched to the 8-pin connector used on Caterpillar, ASV and TEREX skid steers.
- Direct plug fit, no splicing into the machine loom.
- Wire tool for pin adjustment included.
- Built for EZ Spot UR hydraulic function attachments.
🔑 Why the 8 Pin Caterpillar/ASV/TEREX Wiring Harness Matters
- Count pins, not badges — buying by connector rather than by brand is what stops a Caterpillar owner ordering the wrong harness twice.
- Matched to the connector, not the attachment — picking by machine connector is what avoids a harness that physically will not plug in.
- Wire tool included for pin adjustment, so the harness can be adapted during installation rather than returned.
- Keeps a second machine running — crews with two carriers often buy a second harness so an attachment moves between machines in minutes.
- Built for the EZ Spot UR hydraulic function attachments specifically, not a generic auxiliary lead.

Specification Value Designed for EZ Spot UR hydraulic function attachments Included Wire tool for pin adjustment Connector 8-pin Machine fit Caterpillar, ASV and TEREX skid steers with an 8-pin connector🔗 What the 8 Pin Caterpillar/ASV/TEREX Wiring Harness Works With
The 8 Pin Caterpillar/ASV/TEREX Wiring Harness is designed for EZ Spot UR hydraulic function attachments — the rotating bases and the tool heads that run on them. It is the electrical half of the installation: the hydraulic hoses carry the flow, and the harness carries the switching that lets the operator control rotation from the cab. EZ Spot UR offers nine wiring options so the harness matches your machine’s electrical connector: the Universal Skid Steer Wiring Harness for most standard machines, the 14 Pin Wire Harness for Cat, Bobcat, Kubota, John Deere, Case, New Holland and Takeuchi machines with a 14-pin connector, the 8 Pin Caterpillar/ASV/TEREX Harness for those three brands, the Single Pole 7 Pin Bobcat Electrical Harness for 7-pin Bobcat machines, the 7 Pin Intermediate Harness and Intermediate Tool Wiring Harness where a tool-side lead is needed, the Cigarette Plug In Universal Wiring Harness where no auxiliary connector is fitted, and the Radio Remote Assembly for Telehandlers.

❓ 8 Pin Caterpillar/ASV/TEREX Wiring Harness Questions, Answered
My machine is a Caterpillar — do I need the 8 Pin or the 14 Pin harness?
Count the pins on the auxiliary electrical connector rather than going by the brand. Some Caterpillar machines use the 8-pin connector this harness is built for, shared with ASV and TEREX; others use the 14-pin connector shared with Bobcat, Kubota, John Deere, Case, New Holland and Takeuchi. The pin count decides it.
Does this harness fit ASV and TEREX machines too?
Yes. Caterpillar, ASV and TEREX skid steers share the 8-pin auxiliary electrical connector, so one harness covers all three brands where that connector is fitted.
Do I need a wiring harness at all?
If your attachment has a powered rotation function, yes. The 8 Pin Caterpillar/ASV/TEREX Wiring Harness is what lets the operator switch rotation from the cab. The only reason to select None when ordering an EZ Spot UR attachment is that you already own a working harness for that machine.
What if I buy the wrong harness?
Harness choice is determined by the electrical connector on your machine rather than by the attachment, so the safest approach is to check the connector first. Every EZ Spot UR harness includes a wire tool for pin adjustment, which covers minor pin-position differences during installation. If you are unsure, send us your machine make and model before ordering.
Can one harness serve two attachments?
Yes. The 8 Pin Caterpillar/ASV/TEREX Wiring Harness connects the machine to an EZ Spot UR hydraulic function attachment, so if you run several tool heads on one carrier, a single harness serves them all. Crews with two machines usually buy a second harness rather than moving one between carriers.
