I have a 98 f150 with stock motor and trans. Just back halfed it with fuel cell. Did a dash with auto meter gauges and now getting ready to take to wiring. Will the wiring company be able to use my stock wiring harness to plug into the gauges and fuel tank? Also did upgraded 2014 bedsides. Just curious if they will want a full wiring job or half and around ballpark cost range. I don’t think I need full mil spec stuff. I’m more a weekend warrior and grocery getter. Thanks for any help. I’m from temecula area.
