Hello.
My plan is to install the 6.4 hemi and tremec Tr6060 to my 1970 plymouth gtx
I have all the wirings, boxes, cluster, fuel pump, start button, key fob and pedals from the 2021 dodge challenger
Can you suggest what is the best way to make it work?
If i like to use the stock wiring, ecm, bcm and cluster can you program unnessessary functions away? Like abs and everything which light the fault lights.
Or should i use only a stock engine wiring and send the ecm to you for the reprogramming it to stand alone model and make the old scool cluster and wiring?
Or should i throw all the wirings and boxes away and buy standalone engine management kit? Best regards Toni

We highly recommend going stand alone and using your factory gauges in the GTX. We have successfully done the full gauge and control module swaps, so it can be done, but for simplicity’s sake. It’s often not worth it. The timeless look and function of your 1970 instrument cluster will always look good.
