Papa Indy 105 pin 10 is the Orange serial data bus wire ................


Papa Indy 104 pin 19 is the Pink / Brown wire as the ECU provided ground path to close the fuel pump relay

But also look at Papa Indy 104 pin 20 involved in starter rotation enable

and Papa Indy 105 pin 35 involved in starter rotation enable

Could not see a after the starter rotation a inhibit / enable to allow engine to light off / running

Look for missing 2 pinching tabs on the socket side

Give a slight tug on the wires as corrosion can exist at the hidden socket to wire crimp as this is a unwanted water leak from above path

 

Look at Papa Indy 104 pin 18 on the ECU as this is the ECU provided ground command to close the large # 5 right ECU controlled relay that both brings power ( used at all times ) into the ECU . powers the fuel injectors to open and 1/ 2 of your engine sensors

This large relay must click in your finger tips with key in run and or relay removal as a single person operation with key in run

 

Sorry Parker, but which relay are you referring to?

 

You can swap this relay with the same part # LNA6706 used for headlights , fog , or A/ C

The mounting position of these relays can be easily mixed around
