Product Questions & Answers

Q:Is this the full wiring harness?
Demarcus T.
A:BEST ANSWERHi Demarcus, Glad to assist you. It is a universal type of wiring harness for project vehicles such as hotrods or anything similar. It is not a direct-fit vehicle-specific part. We do not carry direct-fit wiring harness assembly for most vehicles on our online catalog inventory. Show less

Q:Is this harness used for the direct injectors or the port Injectors? If it isn't for the direct Injectors what's the correct part number for them? Manufacturer #558-211 is the part number for it, is 558-210 the correct ones for direct injector? Show Less
Khary H.
A:BEST ANSWERHi Khary, thank you for reaching out. We are unable to answer your question accurately due to a lack of information. This product is a generation III Hemi injector harness for vehicle applications with Bosch/Jetronic and Holley injectors used for upgrades and racing for HP EFI & Dominator EFI. However, part number 558-210 is a generation III HEMI injector harness for models with stock/USCAR style injectors for HP EFI & Dominator EFI. Please call our parts team at 1-866-529-0412 and provide the complete vehicle information. We'll be more than glad to help you look for the correct part. Have a nice day. Show less
