exactly what i wanted

It does exactly what i wanted it to, if i want i can pull out my new deck and swap it for my old one with out having to redo or change any of the wires, just unplug the new and plug on the old (after proper installation of course)

Don't hack your wire harness! Get this!

This made the install so much easier! This is a must have. Everything is labeled and the instructions/diagrams were very informative. No need to struggle with cutting,crimping,soldering, or heat shrinking in the vehicle. You can do everything comfortably at a table or workbench, then plug and play. Great product!

Gregt Business to Deal With!

We have had no issues with Sonic Electronix until recently. We had moved from my previous address 3 years back and UPS not Sonic Electronix shipped the item to the old address rather than the current address. Having a conversation with Sonic Electronix quickly resent me the package and the situation was under control. Sonic Electronix has been good business people and highly recommend them to business small or large.

sent wrong part after using the guide and told i need to pay return shipping!

IDK how well this product works, because it was not the right one for my truck, even though i used there fit guide to make sure. now they want me to pay return shipping that costs more than the item to send it back for a refund. I contacted them over a week ago to take care of it, and was told it was being sent to a manager. Now that i have called back, they inform me that it was refunded as a store credit, I never received any info on what was going on. It is also not showing up on my account that it has been refunded for a credit......

Will not fit a 92 S10 pickup

This is a good solid connector. It was recommended for the 92 S-10. I ordered it as recommended. Soldered it to the harness of the aftermarket receiver. No Go! I found out after pulling the stock receiver.

harness

Good little wire harness.. no issues just wire it up with the head unit one before you put it in. Don't do it half arsed! Use shrink wrap and the proper tape to do it, watch videos if you don't no and ask around. Don't make it harder than what it is.
