Is their a company that makes these?

Since my bodydrop and all that good jazz is done I would like to relocate my computer on my 97 Sonoma (DOA) so I can fit my york engine driven unit in there. Is their a company that makes a plug where you can extend the factory wires and then just plug right back into the factory computer or am I going to have to cut each one of the bitches and reconnect them this way?
