I have a 1990 s10. its got a 350 in it.i just bought a brand new accel hei distributor but dont know how to wire it.
do i need a spark box?
msd?
can i hard wire it?
You shouldn't need a spark box because thee coil is located in the dist. cap. You need to run a 12v switched power source to the side of the dist. cap that is marked dist. if it isn't maked it is the term. that is on the front right of the conector pad. the one on the left is for hooking up a tach.

buy the new distributor and connect the wires up
all the details are in the box
you can buy the pointless internals to replace the points in your old distributor
go to the wreckers and buy a pointless distributor for your engine
Hello! The Mad Street #8362 is not for a seven pin, computer controlled engine...It is for a five pin distributor...I believe your engine has a seven pin connector...The correct distributor is a: MSD Ignition 8555Guru...saailer
HEI distributor and burning coils,it in you connection first make sure you install primary and secondary prorperly as it comes out of the cap , and inside the cap wire from modules dont make contact if you are burning its from primary circuit, this is the (B+) or (battery most likely), your secondary is your tach and that need to switch from postitive to negative for it to create spark obvously if tach was grounded or applied power you wont start,but there are times the condensor in the distributor does stays fixed and shorts out the coil (replace that condensor its for suppression) when the condensor is replaced run a fused direct wire at B+ (from ignition) run the vehicle and monitor the tach wire and check to see if that get hot
ok looking from the driver's side of vehicle at your distributor. There is a power wire (which on most accel or msd distributors) on the right in the first row the wire connection on the left is for a tachometer the row behind it can either have 2 or 3 wires most of the time 1 is usually black and it grounds the ignition coil module inside the cap the other wire/s tranfers power from power connection to coil. A hei or high energy ignition system uses the coil module to amplify the voltage from the standard 30k volts to about 45-50k volts
'56 engine was likely a "blue flame" engine that had a points type ignition system. If someone installed a HEI setup in there, you need to know what year vehicle it came from. The old system used a hot wire from the ignition switch to the (+) side of an external coil...the (-) lead went to the points. The most common conversion uses the same (+) wire but it then connects to the "batt" terminal on the distributor cap.(coil is inside) There are no other wires involved except for the short harness that goes directly into the distributor that connects the coil, pickup coil and control module to each other..
