yes have to make your own from what i was told for the oil psi, coolant temp, and intake air temp. but they are all the same thread 14x1.5mm they told me and on the 01 02 you have to get the haisley cam position sensor bracket for the p-pump conversion and install a 01 02 cam gear with tone ring on the 12v cam is all i can come up with. all gauge are supose to work then remove check engine light bulb. and will have to hard wire the fuel shutoff but i have a complete doner truck. so i have the relays and peices of the harness i need.
