You'll need to retro your neutral safety switch and reverse lights wiring since the 48re NSS is completely different from the 47re. You'll need to use the 47re shift linkage/bracket and you'll no longer need a TV cable. Everything else should bolt in place, then you need to wire power, ground, and tps signal to the pcs controller.

There is a Sonnax piece that you can thread into the NSS hole of a 48re to convert it to a 47re style NSS. You would just need to switch over the rooster comb on the valve body to the 47re style and it should work like normal with no rewiring.
