Question High or low imped injectors????

Ok I have a 88 Vert Built 3/1988... I've been searching and found that between 86-87 N/A injectors are Red Low imped squared with a center notch ... Now on 88's there High imped but not all are high imped due to vin splits and and date of production. (Sorry I worked in dealerships as a tech "VW and Saturn" and in the parts department made it easier on all the techs to know what part was what.) On the car are Red Squared offset notched injectors, So are they High imped, or Low imped, I have the resistor box to my knowledge. The 4 wired box that plugged under the Air box heres pics so you'll see I need to know, if so I'll get the injector low imped injectors for my engine swap. If there high and all is good I can continue and just get my Wiring harness and use the S5 injectors. Last question what About the little box, I was reading up and I'm not sure it its the Resistor box or a different sensor!!!

The Resistor Box??? Or what is it!!!

plus the other wires the place of it on the frame where the air box should be

Offset squared red injectors

you can see the difference I picked this one up at pic-a-part

last pic of it head on... So what are the ones on the car High or Low??? I need to finish this S5 Turbo swap I'm goin to get my wiring harness so I need to know if I have to get the injectors engine is on it's last leg... Thanks guys

You could always use the ohm meter to measure the impedance of the injectors and your first pic might be the Air Bypass relay which would have four wires that are BR/Y, R/Y, B, and B/W.
