do the TPS and EGR share a wire??

[85cleangtvert]

i have a 88 5.0. I thought my EGR was bad. It still might be. But I was checking the wires. I have a orange colored wire coming from my EGR as well as my TPS. They are both go to a blue connector that connects to a single orange wire. The connection at the blue connector wasnt very good anyway and had wires exposed that were covered by electrical tape... before I put these wires back how they were, I want to know how they are supposed to be and if it is correct or incorrect. Thanks!

Sound/looks correct accoriding to the two diagrams I've looked at. The orange/white wire is the Vref for the EVP,TPS, and the MAP/BAP sensors.

They share 2 wires, VREF and SIGRTN or ECM provided ground. GL
